Title: Where is the OBD2 socket on a 2004 Astra 1.6 petrol?
Post by: terry paget on 03 November 2018, 15:55:18
Bought this car today, MOT failure, engine light on, and cannot find the OBD2 socket.

Must be within reach of the driver by regulation... so if not under the steering column try the centre console area, On the later Zaf it was somewhere in the lower centre console IIRC so probably the same for an Astra

There’s a plastic cover underneath the handbrake lever. Pull it up and your prize will be revealed 👍

Try not to brake the clips though, it kind off pulls up one side then slides off the other.

Good question!  Given that it has rudely been described as Victorian by our aristocratic member from Lincolnshire, it might be OBDI.  :-\

It has a big round plug and I have to use an adapter to use my code reader.  :)

OBD sockets(whether 1,2 or EOBD) are trapezium shaped, and must be accesible from the driver's seat.

If Sir Tigger has an E39, the early model definitely had a round (OBD) Diagnostic Port in the engine bay but later E39's have the traditional rectangular socket behind a panel on the dash by the drivers right knee (UK spec). My mate had both models so I know that's the case.  :y
I believe that some models ended up with both connectors present. If the dash connector is there, it will be behind another flap with OBD marked on it.

Basically 2001 on in europe ;)

My '51 525s was under the column as described above, as is the Trolley... The trolley's stalemate has a socket under the bonnet but only late models(' 98/99) have one under the dash, and then it's pot luck ;)

Re the Beemer, as have been mentioned, its only post 2001 for petrols and post 2003 for diesels that European sold cars had to be EOBD (Euro form of OBDII, virtually identical, but sometimes enough to confuddle crap code readers).

EOBD includes socket spec, protocol specs, and socket location (within 1m of the steering wheel, in the cabin).

Obviously, the manufacturers were aware of this spec coming into force, so most put the socket in place earlier, when a new model/refresh was launched. Some, such as Rover, did not enable EOBD on the actual ECU until the date it came in though.

Pre EOBD fuel injected/engine management cars usually had some kind of diagnostics capability, but the socket could be whatever and wherever the manufacturer chose.

Your Beemer probably has both types of diagnostic socket,the one under dash is the modern type but probably only good for engine diagnostics,the big round one under bonnet for all the other systems  :y

I suspect so. My cheapo reader said 'Lean mixture bank one'. The car has 2 lambda sensors, so could be either. I cancelled the code and it has not reappeared yet, but I cannot go far until I get an MOT certificate.

Once again, that does not necessarily mean that the lambda sensor is the fault. Whats more likely is that the sensor is reporting a fault further up the system. Changing the sensor will not fix the fault.


Reading the codes is just the start of the diagnostic procedure.

It clearly passed on emissions, it failed MOT on engine light on, which I did not not think was a failing matter. It also failed on horn not working, LH side light not working, and both rear discs seriously worn. The horn now works, I have changed the sidelight bulb, the rear discs don't look bad to me but I have ordered new on e-bay, and the engine light is off at the moment. This car is the spare, so I can, in my own time,  change the oil and filter, cambelt and water pump. It's novel to work on a car with no rust, and immaculate externally! My son Jonny is very pleased with his Astra, I shall change his cam belt when I have sorted this car.

Brake discs have got to be stupidly bad to fail. There is a tester I know (not my garage) that pretty much fails discs on every mot. I don’t think he understands the term ‘minimum standard’

I agree, but will a different tester pass the car if he is aware it has failed before on brake discs? I have seen the MOT testers guide , and 'pass and advise' is all these discs warrant.

 4.5" Angle grinder. You must have one, as you've got an electric welder.


You spent more time typing the post quoted above than you will removing both droplinks. Don't make this complicated!!

What Nick said.

You may have luck with the Allen key / holding the nut if u soak it in wd and wire brush the threads. However if it gives u any hint of fighting then see Nicks post. Just do it carefully so you don’t cut the roll bar and/or strut link mount flange thingy. 👍👍👍

So do I, which I use first. But if that's at all difficult, I go straight to the grinder as it saves a load of faffing about.

I have changed many drop links on Omegas, always by brushng off the mud and external rust, spraying with WD40, and with a socket spanner on the nut and a 16mm spanner on the flat, undoing the nut. But it has been hard work, especially on the upper one. I have never used heat, but that's an option. The angle grinder sounds most sense, as long as I can get access.

They’re no different mate 👍 if anything they’ll be easier if they’re the crappy plastic ones. Rip the plastic arm/link off. Mole grips on the newly exposed ball joint. Buzz the nut off.

Or. If they give any trouble use angle grinder straight down the centre of the nut. Tension is then lost and again get ya mole grips on the ball joint and off it comes. 👍👍👍

Interesting to note that while I heard front end clonking on the journey home, drop link bushes failed presumed, it was not picked up in the MOT test. I could never detect drop link failure in a stationary car either, but my local MOT tester can. How does he do it?

You will Struggle to find play with one corner jacked but with whole front end raised its easy to spot the wear

So with front end of car supported, wheels hanging down, if I grasp the drop links I should be able to detect play.

both wheels hanging down ,Pry bar under the tyre ,raise the wheel ,hand on one joint at a time (making sure you don't squish you fingers) you should feel play, the same as if you hold a worn out track rod end . if you a have helper, then you can look for play  :y
often ,the ball is worn ,sometimes the nut is not tight enough and play is in bolt hole.
strut top mount rubbers go soft(common) ,bottom ball joints wear ,broken spring,loose strut bolts,all the usual suspects
rear suspension torsion bar ,so no drop links ,common to have play in the bush of the shock, at 100k + the shocks could well be past effective anyway ,so worth checking damping operation in both directions   :y

Grab the bar next to the drop link and push/pull the hell out of it. You’ll feel the play. I’ve personally find that on the four poster (ie not jacked up) you can really feel the play. The mot tester will find the play this way 👍

The symptoms, diagnosis and fix are all the same as the Omega (and pretty much every car since British Leyland collapsed).

The following thought is meant in kind concern rather than a dig or a criticism, but try as I might, it will sound, at best, blunt...

I wonder if I am alone in thinking that Terry might be starting to show his age :-\
Perhaps if his kids read this, that they might pay closer attention  :-\

MMMMM  :-\  :-\
I don't know how old Terry is ,
I don't know what arrangement he has with his family ,what he gets in return for sorting their cars ,which they are obviously too busy and not knowledgeable to sort themselves ,
I do the family cars because an MOT is a minimum standard  snapshot of roadworthyness 1 day a year, and on the instances my family have taken cars to garages ,it's been very expensive in money and cost me time anyway ,sorting poor "fixes" the garage have done
recent example ,the clutch on the french car , would have taken me a day or 2 , I was busy,did not fancy the job , the cowboys made a hash of it, I spent a lot longer than 2 days sorting out the refund claim,engineer's report,emails,phonecalls etc , then I had to find a replacement vehicle ,check it all over and sort any issues out .

Terry does ask questions about how to do things , this is a forum , many people ask questions , gleam useful information ,not covered in the  H̶a̶y̶n̶e̶s̶ ̶j̶o̶k̶e̶ ̶b̶o̶o̶k̶  manual .
Terry is new to astra maybe a bit daunted by the unknown , many of us have had them and know common issues etc and are happy to help with advice, in the same way that I'm new to the V6 and ask for advice

this is why "the OOF" is a great forum  :)
DG and many others have pointed me in the right direction , for which , I am very grateful  :)

 it's up to Terry to decide how old he is / if "Terry's garage for family" should farm more work out  ;D or if he's happy to potter about ,keeping him active , beats playing golf  :D ;D

He's about twice my 42 iirc, and having seen just how quickly alzheimers can take hold, I am concerned.

Obviously it's upto himself and his family as to how they arrange themselves, and I hope that I am way off the mark...

Certainly there are plenty of other people here of similar vintage whom I have had the pleasure of meeting, Shackeng to name but one, who show no signs of slowing down which is why Terry's questions stand out as he has previously been very capable  :-\

My forum profile reckons I am 79, wife says that's about right.

 Forgive me if I ask naive questions, I begin to worry when I cannot find the OBD2 socket on a car. Haynes was no help.

I remember watching an MOT tester, with car on a raised ramp and jacked up off its wheels, raising a front wheel with a bar while groping in the suspension; now I know what he was doing. Why did not the last MOT tester spot it I wonder?

The bar is used to check for any play either in the hub or suspension components.

Ball joints usually pass one year with a "dust cover cracked but currently preventing ingress of dirt" followed by failure the next year because the rubber boot has failed and all the grease has washed out allowing catastrophic wear :y

Most MoT failures are a direct result of laziness or ignorance.  ;)

Loosened rear wheel nuts drove up and down, that loosened, great. today I am trying to change rear discs, but they too are stuck on. I have tried hammering it, tried my 2 legged puller, no joy.

This car failed its MOT in October 2018, I bought it as failed MOT spares and repair. I think Haynes might have told me where the OBD2 port is. Thank God for this forum.

You can see in the pic that the grub screw has been removed, 10 o'clock on the disc. That too was hard to remove, I think thse brakes have not been touched since new, nor the fluid changed. The woman who sold it to me said, with pride, that it had not been serviced for a lomg while. Thanks Henryd. I will paint some brake fluid around the central hub and leave it overnight.
I have had similar problems on Omegas, even after backing off the handbrake adjuster all the way. In the morning I will try again, with 2 hammers, bashing from both sides. I am reluctant to use heat near the wheel bearing.

You would need a massive oxy-acetylene torch to get enough heat through the disc and hub to affect the bearing :o  Just waving a butane torch around won't do anything worthwhile, unlike a bigger hammer which will.

This car comes with an amazing service history. Since 2014 it has had one owner. She appears to have changed what was necessary to keep it going and get it through MOT tests, but never changed the oil. She did change the cambelt, tensioners and water pump on purchase, and has since then changed droplinks, plugs, fuel pump, crank sensor, steering joints and tyres as required. The oil was seriously black. I ran the engine for 10 minutes to warm up the oil, then drained it for 3 hours. I changed the oil filter and put in new Trade Club 5W30 oil. Checking the level, the oil on the dip stick was still black. Oh dear.

When I changed the oil last Wednesday in my other Astra, after oil change the dip stick showed clean oil.

I wonder how long this engine will last?

Thanks for advice. After brake fluid overnight and a bigger hammer, the brake disc came off. N/s brake is fully assembled, but I discovered I could not retract the brake piston without a special tool to screw in the piston, which I do not have. I used the big hammer instead. All is now assembled, but I cannot turn the wheel. Will it free up under engine power, or do I need the special tool?

Check the MOT history :y
has it failed on emissions in the past ?
how is the engine now you changed the oil ? any noisy valve lifters ? knocks etc ?  smoke when the engine is up to temperature ? is this the 120k miles one ?

5w30 fully synthetic is thin and will flush sludge from all the engine IF it is there (if engine has done short journeys,not had regular oil changes,had thick oil in the past)

I've had this in the past ,a 1.6 with only 80k that a garage put flushing oil in to reduce emissions then fully synthetic 5w30 (it did not work, just made it worse ) all the sludge just stuck in the oil control rings ,jamming them in the pistons  >:(
 it smoked like a steam train when warm, I got the car,stripped it ,new rings ,cleaned sump etc and found the emissions fail was down to a clogged injector  ::)

your car may have had thick oil in or not been changed enough(very likely from what you say) ,
hopefully a couple of oil and filter changes will resolve it .

you need the tool
you may have damaged the caliper by forcing it because it has a ratchet handbrake mech too (so handbrake off,reservoir cap off,rewind tool)
there are 2 slots in the piston to get purchase on to screw it in,
you could fashion a tool ,see if it will turn but they are very cheap
the little cube multi rewind tool WON'T fit these IIRC

I ground an old imperial spanner to fit the slots perfectly and used an adjustable spanner to grip that and turn it , but that requires turning and pushing the spanner which requires 3 shredded wheat for breakfast  ;D
You need to turn it in the correct direction too ,and i can't remember which (and tools are available for both directions so as well as finding one to fit the slots it needs the correct thread)
probably youtube videos and a google search will find the best tool if you don't want to buy a universal set ,like this clicky link (https://www.screwfix.com/p/hilka-pro-craft-brake-rewind-tool-kit-20-pieces/9796r)

I recently did the rear calipers on kitty and had to rewind the piston.  Clockwise is fairly typical across the market and I used the small cube tool I bought from the local factors.  It wasn't a perfect fit but I created a clean flat edge for it to bite on to and that did the trick.  A pig to get started but once moving it took half a dozen turns to get back far enough for the new discs and pads.

The "cube" definitely won't fit 5 stud ,so doubt it will fit 4 stud brakes and it requires a strong force to keep it engaged ,

Thanks to all for advice. I bought a Laser piston retracting tool from a local factor and it did the job. Rear discs are now changed, so that's the car ready for MOT. However I must check the engine light stays off, and I suspect a drop link is dodgy too.

I liked the Astra high tech wear sensor, a simple spring steel tongue that will make a scraping noise against the disc when it touches it. It is on the front right corner of this pad, sitting on this little worn but MOT failing disc.

I have not changed the brake fluid yet, though I intend to. I will check whether it looks obviously contaminated.The MOT was carried out in Warminster by the previous owner. I bought the car as a spares and repair MOT failure. I did not notice any smoke on engine start, either before or after the oil change. My plan is to check for dodgy drop links, change any I find, perhaps polish the headlights, then submit for MOT test. There's no hurry though, so I might as well change the brake fluid now. I noticed the rear calipers had rubber caps on the bleed nipples, suggesting never used; I gently applied even torque to undo one of them, and it turned! I shall change the oil again soon, after 100 or so miles.

Quite so. But as a frequent buyer of used cars I find more often than not one or more bleed nipple cap is missing, which suggests that the brake fluid has been changed at least once.
Haynes instructs that on pushing back the caliper piston I should open the bleed nipple and clamp the brake hose, lest grit get back into the ABS unit. Not done that before, but never suffered ABS unit failure on that account. Mine fail electronically.

Always struck me as a bit of an odd one as unless the MOT'er bleeds a brake caliper, how does he know that the owner hasn't dunked a sheet of kitchen roll in the brake fluid reservoir to suck the old out and then topped up with fresh the day before. It must happen surely.  :-\

It's good practice as it removes most of the dead/gungy/sludge fluid from the caliper...

Actually makes a difference to brake feel as well :y

Using the pipe from an ezibleed kit, pop one end in a jar of brake fluid and support it below the caliper, then attach tother end to the nipple. Crack it half a turn and wind/push* the piston/s in. Once piston is solid, close the nipple securely.

*As appropriate... In the case of integral handbrake mechanisms, wind.

Agreed.  :y  It's also a good indication of how free the piston is in the slider as there should be very little resistance doing it this way.  :y

I do as DG ,the jam jar with small amount of old brake fluid in but use the tube for fish tank air stones(under the fluid ,so air can not get drawn back up) ,very cheap ,but effective method  :y
Not a fan of easybleed pipes and valves,the valves stick .
I NEVER clamp a flexi , just bleed the lot through .
And it will make a noticeable difference if the fluid is old (potentially 10 years old or more in Terry's case with the 2004 astra) and there was a service bulletin re brake fluid change  on astra of that era.
  If you have ever done the brake fluid change and seen the colour of the fluid that comes out the calipers, you'd be a convert to regular changes.
 yes, some people may suck out fluid from the reservoir and put fresh in to fool the NT (MOT tester) ,If it's dirty in the reservoir, just imagine how dirty it will be in the calipers ,plus clutch line(in proper cars with a full compliment of feet controls)   

GOOD LUCK with the test Terry and well done working your way through the jobs  :)

Changed the brake fluid this morning, though the reservoir is white opaque to defeat the MOT tester; fluid came out looking fairly clean too. I have an Eezibleed kit, but still found I had to remove the wheels. I changed the o/s drop link, and found the bottom joint satisfyingly shot.

Cambelt, pulleys, tensioners and water pump were changed October 2014, 35000 miles ago. I see what is surely the water pump bottom right of the engine driven by the auxiliary belt, so there is particular reason to change it with the cambelt. Must grease the tensioner pulley, though.

This car is nearly MOT ready. However, when I bought it (last Saturday) the engine management light was on, and this was listed as an MOT failure matter. After Webby the Bear kindly told me where to find the OBD2 socket I plugged in my simple code reader, read the code (lean mixture bank 1) , cancelled it, and the light has stayed off ever since. Today I plugged in my laptop diagnostic device, and read live data. Code P0621-04 came up as a fault code, Generator Lamp "L" Control Circuit Malfunction. O2 sensor 1 was switching RICH/LEAN/RICH /LEAN satisfactorily, but O2 sensor 2 was steady on LEAN. Engine light remains off. My worry is it will come again.

What should I do?

Is the fault code stored or present ?
if you clear the code ,does it come back on ?
in live data , what is battery voltage ?
with the engine running, what voltage is at the battery using a volt meter ?
does the battery light on dash light when you first turn the key (before engine crank/run) and go off ,and stay off engine running ?

as you can't test drive ,put your code reader in the car and if need be, reset EML if it comes on as you pull up for mot  ;D

In live data, battery voltage is 14-3-14.4 volts

Battery light comes on initially, goes off on engine starrt and stays off.

Terry, sorry I have come to this conversation a bit late. Your Z16XEP fault will keep re-occurring. In somewhere between 60 and 100 miles P0170-2 will show. It's a common fault i have just sorted on mine. The EGR recirculation channels in the intake manifold where it butts the cylinder head become blocked preventing the gas from entering the manifold. The ECU discovers this and finds it cannot enrich the mixture to accommodate it in the warm up cycle and throws the code.

Solution, take it to bits, about 2 hrs work, clean it and put it all back together again. You might also find some muppet has blocked off the EGR channel from the valve. If so this will have the same effect. Having done this, if the fault re-occurs then the EGR is not functioning correctly.

This car comes with an amazing service history. Since 2014 it has had one owner. She appears to have changed what was necessary to keep it going and get it through MOT tests, but never changed the oil. She did change the cambelt, tensioners and water pump on purchase, and has since then changed droplinks, plugs, fuel pump, crank sensor, steering joints and tyres as required. The oil was seriously black. I ran the engine for 10 minutes to warm up the oil, then drained it for 3 hours. I changed the oil filter and put in new Trade Club 5W30 oil. Checking the level, the oil on the dip stick was still black. Oh dear.

When I changed the oil last Wednesday in my other Astra, after oil change the dip stick showed clean oil.

I wonder how long this engine will last?
Not long I fear. Took car for MOT this morning, it struggled on emissions, then began to rattle. Tester stiopped the engine, asked me what he should do. I said skip emissons, do the rest of the test. He drove the car onto the rollers for the brake test, the engine stopped and would not restart. It appeared to have seized. We agreed it should be allowed to cool down. I rang my son for a lift home.

Post by: ajsphead on 13 November 2018, 14:16:32
If the engine had seized I'd expect it to give a series of fault codes. It could just be a blocked fuel filter or a failed fuel pump/fuse. Or, if it hasn't been serviced properly the spark plugs could be so far gone there's no electrode left.

The rattle might be nothing to do with it. Early twinport engines had rubber edged flaps in the first stage of the intake manifold. The rubber wears away and people think the engine is rattling. It's not. A later version, same pt number different serial number is the revised version which is fine.

Don't give up too soon, might be a simple fix.

I went to collect it 4 hours latre, with a tow rope and an Omega estate. It started, but rattled once it got warm, and wanted to stall. I managed to drive it the 2 miles home, by which the low oil pressure light was on, along with several other warning lights. I guess the engine is wrecked.

I think you hit the nail on the head
5w30 will strip all the dirt from a neglected 100k+ engine :'(
indeed, dropping the sump to look would be worth the time

knock top end ? oil starved lifters perhaps
you could try... sump and pick up cleaned,plugs checked ,fresh filter and thicker oil ?

Check the MOT history :y
has it failed on emissions in the past ?
how is the engine now you changed the oil ? any noisy valve lifters ? knocks etc ?  smoke when the engine is up to temperature ? is this the 120k miles one ?

5w30 fully synthetic is thin and will flush sludge from all the engine IF it is there (if engine has done short journeys,not had regular oil changes,had thick oil in the past)

I've had this in the past ,a 1.6 with only 80k that a garage put flushing oil in to reduce emissions then fully synthetic 5w30 (it did not work, just made it worse ) all the sludge just stuck in the oil control rings ,jamming them in the pistons  >:(
 it smoked like a steam train when warm, I got the car,stripped it ,new rings ,cleaned sump etc and found the emissions fail was down to a clogged injector  ::)

your car may have had thick oil in or not been changed enough(very likely from what you say) ,
hopefully a couple of oil and filter changes will resolve it .
No mention of emission problems in service records or old MOTs, or I would not have bought it. In the MOT fail in October emissions were not mentioned. I was therefore surprised this morning when the tester failed to get it through the emissions test. Three attempts with sustained high revs failed, got the engine and the oil hot, then it rattled. With hindsight, the oil remaining black after oil change warranted more investigation.

I do not understand why if failed emissions, after passing them a month ago, unless my oil change caused it.

Mine passed it's emissions for the last owner with 2 dying lambdas and the EGR blanked. He was lucky as it was before EML on became an MOT fail. Dropping the sump is fairly simple so I'd start there too. The reasons for emissions failure can more easily be sorted when (if) the engine is running properly.

Not familiar with this model, but that's the usual procedure. Just depends if anything's in the way.

It would be interesting as a post-mortem if nothing else, but you might find that you can clean out the oil pickup and sump, fresh oil and filter and there's no lasting damage. Unlikely, perhaps, if it's been driven with the oil light on for any distance, but who knows?

I think the front exhaust needs moving and a couple of bolts into the bell housing + sump bolts to block
and the pick up pipe is part of the sump ,so sump gasket requires a good seal around where the pick up meets the block and pump or it will suck air rather than oil
which will give low oil pressure ,the oil pressure sensor could be crudded up or the oil is too thin when warm (just leaking out the big ends and mains and not even getting to the head :-\
there is a diaphragm in the rocker cover (like a crank case breather one way valve) can split

first thing i would do is check the plugs ,if very oily  :-\
(oil passing rings,oil control rings stuck)

do you have a print out to say the emissions where done a month ago ? what readings or did the tester skip it  :-\

No, I do not have an emissons print out from the Octobe MOT.
I am in the process of dropping the sump. I have removed the exhaust and the under engine cover. I am now draining the oil over night. It is black, thick, glutinous, not like lubricant at all. I know it is cold, whereas I drained the original oil hot, but even so I am amazed at the state of it.

Sorry for being simple 😂😂😂

So the car was MOTd in October of this year? Presumably failed on something/ some things. You’ve subsequently done said work. New MOT test this week and emissions fail plus the engine rattling?

When you do emissions it is then down to you as the tester to manually enter that failure on to the list of defects; the results aren’t auto-uploaded. So irrespective of the lack of an emissions sheet it either passed on emissions or the tester omitted to input them as failure items on the refusal certificate 👍

CO. Occasionally the CO came within limits, but as tester kept trying to get all 3 parameters within bounds, the car got hot and began to rattle.End of test, end of car. On each attempt all the parameters went 'all over the shop', occasionally came near passing, but never made it.

I am trying to drop the sump. I have removed all the bolts and screws I can see attaching the sump to the block and the bell housing, but it did not fall off. I hve given it tentative taps with a hammer, but it stays put. Is there a trick to release it?

Probably glued on with instant gasket - it was a nightmare to get sumps off the 1ZZFE in the MR2, usually needing a chisel or wide scraper and a lump hammer!

scrape part of the gasket out with a Stanley knife, then pry the sump off with a nylon wedge in the hole.
You could knock a screwdriver into the gasket and pry the sump off that way. But you'll probably have to straighten and or dress the edges afterwards.

'Drop the sump' sounds trivial, but it's not. Even removing the front exhaust took a while, and involved blowtorch and angle grinder. I believe I have now removed all the sump retaining screws and bolts, but the sump has not fallen off. I am only doing this to inspect the oil pickup strainer, the car is scrap.

I shall pause at this point. I need the garage for other jobs. Jonny is here this weekend, I must remove the rear wheels froim his Astra.

Here are all the screws and bolts I removed.

Glad you like the 1.6 twinport. I was surprised to read in Haynes that it has variable valve timing, very high tech. I imagine it would benefit from clean oil. My son Jonny likes the sound system too.

The service history contains no mention of an oil change in the last 10 years. So once the oil filter got blocked, and the bypass opened, all the debris in the oil was recirculated. I did observe, and comment on this forum, that whereas after the oil and filter change on my first Astra the dip stick showed clean oil, on this Astra it did not.

I imagine it would have taken several more oil and filter changes to remove all that debris from the system. I should have changed the oil and filter again on seeing that dip stick, and again and again until the stick showed clean oil. Silly me. I shall not make that mistake again.

I would imagine that the oil pick up in the pic needs soaking in parrafin or similar to wash it out ?
Might be best to check with someone who knows these engines though.Then, either a few quick oil changes with cheap oil to clean things out, or run some flushing oil through it, if you can still find such a thing.
May be wrth dropping the sump again after that as it may well be full of crap again.  :-\

Hindsight is a wonderful thing  ;D
strainer still looks clogged up ,backflush it into a container and see what goodies you find  :y
if clogged up ,that would explain the oil light etc
I would try a new oil filter and oil, rather than just write this astra off ,rtv or silicone the sump back and give it a go .
VVT is on later models ,early z16xep just has regular cam sprockets  :y
regular oil changes ,sooner than service interval is money well spent in my opinion .

If that mess was after an oil change :o then several changes wouldn't really have helped: pulling the sump and physically removing all off the sludge would have been the only realistic option. Quicker and cheaper too.

Thanks Nick, I am sure you are right. My only clues were the vendor telling me she had not had the car serviced 'for ages', and the ominous appearance of the dip stick after the oil change. Then I had never removed a sump, so I gamblsd on the car passing its MOT, and planning to do another oil change after a few hundred miles. Next time I see a black dipstick after an oil change I shall think twice.

It reminds me to change the oil on my other cars in good time too.

Yes, of course. Everything needs to go back exactly as it was.

.. and whilst the top end might be starved first, the bottom end will be the most prone to damage when the engine's driven under load.

If the top end has suffered, popping a 2nd hand head on would be an easy fix. If the bottom end bearings have suffered, it probably need a complete stripdown and rebuild.

Yesterday I bought another Astra 1.6 H, 111000 miles, full MOT, £795. On getting it home I promptly changed the oil and filter. Dipped the oil, it was not bad, but not completely clean either. I see in the service record the oil and filter have been changed 5 times since Feb 2017, in 11000 miles. Could it be Astras are prone to collecting muck in the sump? I would drop the sump of this one, but doing so involves destroying the central exhaust. As Nick W observed, the muck in my 04 Astra would never have been removed by oil changes.
What are the points for and against changing to 10W40 oil?

5w30 synthetic is ok for a new engine , but after 100k and 14+ years it is thin and has detergents and additives, if you had the car from new and did regular oil changes then it may be ok , but with a high mile engine ,that may have had cheap or thicker oil  ,or done short journeys ,not getting up to tempreture, sludge and deposits can be washed off(as you proved  :( )
10w40 semi or even mineral (with regular changes ) is thicker ,
I've had vauxhalls since i was 18 ,never found a 100k+ one that ran happy on fully synthetic P155 (5w30)  they smoke ,use stupid amounts of  oil ,IIRC vauxhall official oil consumption on a 1.6 astra g was 1 L per 1000 miles  :o

I'm sure someone will b along shortly to say i'm wrong  ;D but 30 years of vauxhalls under my belt ,none i scrapped for engine problems  :y the tin worm ate em  ;D

Maybe. First Astra I bought was the 2010 160K car which I bought 3 weeks ago, seemed fine, was in and out in a day, and is still giving satisfactory service with my high mikeage son Jonny. This gave me confidence in the Astra and bought more. I have bought Omegas, 2 a year, on that basis, for16 years.
I suspect that Astras and 5W30 oil are less tolerant of missed filter changes than10W40.

GM provide a wide range of suitable oil grades for the engine so it isn't as critical as some. My 1.6 has done 111K has always had 5W30 and is smooth and quiet. it also uses no oil between changes. It's been serviced according to the fixed mileage schedule and used I think really "normally" so i have no reason to change the oil grade.

To my knowledge there are no known issues with sludging so it may be as much to do with how it's driven and the quality of lubricant used and whether it's been flushed at oil changes if needed.

I'd look for signs of swarf and sludge in the sump. I have a simpler way of checking the sump for sludge using a thick gauge wire or thin gauge steel rod with a shortish 90 degree bend inserted through the drain plug hole and then rotated gently across the inside of the sump pan. it's not perfect in that it won't show what's under the baffle but it gives some idea of whether it's fairly clean or slimy and the sump needs to be removed. Even if you pull no sludge out you can feel the rod pulling through it.

Out of interest do you use a flushing agent at oil changes?

Did you suss out the owner to see if:

1. They were trying to hide something or
2. They were paranoid ?

My Omega is knocking on 230k miles, I use 5w30 in it and it doesn't burn a drop.

There is no point over thinking it and the difference in viscosity between grades in not huge anyway. Just use what the manufacturer recommends. I am not really a fan of semi synthetic when you can get fully synthetic almost as cheap these days but then I CBA to change the oil every 3k either. ;)

With an unknown history a few quick changes with cheap oil might be a decent idea in the light of recent experience.

Thanks for your sludge checking tip. I shall employ it.
The first Astra I bought was a dealer p/x to clear; great car. The second was an MOT failed car, no mention of emissions on the fail certificate; I inspected it, no rust, and bought it. It was a 'wife's car', when I picked it up I met the wife, and she proudly announced she had never had the oil changed in 4 years.  The third was bought from a dodgy dealer in Ringwood, but the car came with MOT till 25 Nov 2019, and looked all right and test drove all right. I know buying 10 year old cars is always a gamble, but I have never encountered sump sludge before.

Nothing you have said about the second or third Astra inspires confidence and only suggests that you got lucky with the first one. I for one, would be interested to know how the sump contents compare between cars 2 and 3 :-\

You would do well to spend that sort of cash on ex plod stuff... at least you know exactly what you're getting.

Ex Surrey or TVP from WOMA is a safe bet... 4-5 years old and no nonsense. :y

I bought all my Senators from WOMA, and my second Omega, ex TVP. They weren't as cheap as the rest of my Omegas, though, and they were unique police spec, manuals, no cruise. I have become accustomed to paying less than £1000 for my cars recently, paid £190 for my last Omega purchase. At least Astras don't rust. I wonder what ex-police Astras cost?

They are being retailed from £1,500 up and that's for early Astra Js...

Obviously the nicer cars are well over £2k, but they start somewhere and I would wager that they aren't significantly more expensive at the auction than the rougher/older/higher mileage ones...

What's the point? Car rattled during the MOT, and again on the short drive home, stiffened up too. I reckon engine suffered oil starvation and is wrecked. I shall strip the car for spares, and scrap it.

Removing the sump involves removing the exhaust. On the 04 car I did so with an angle grinder. Haynes advises removing the clamps, applying penetrating oil, hammering a bit and separating the sections. Is this practical? Or does it mean buying a new exhaust? I suspect the sump on the 2008 car is full of sludge. The oil looks dirty already. The car has a year's MOT so I can use it, but I should like to fully sort it.

still using 5w30 then ,despite car 2  ::)
even OOF recommends 10w40 trade club semi for omegas because  it works ,despite vaux saying use P155 fully synthetic 5w30

I guess when you do a few more oil changes you wont have any fully synthetic left and have to use the 10w40 semi  ;D

I could not get the exhaust over the rear cross member, so I sawed it up. Did I miss something?
I bought 20 litres of Vx 5W30 trade club because that was the recommended oil. I put it in the first car, its working fine. I could not imagine what harm using 10W40 could do, now you confirm this. I bought some 10W40 at the same time for the Omegas. Would using 10W40 in the Astra improve lubrication?

to drop the sump, you just need the exhaust out the way , remove the bolts at the front, remove the rubber hangers,move the exhaust out the way ,you don't need to put it in another room  ;D, still under the car but to one side , allowing the sump to be dropped  :y

engines wear,even with manufacturer recommended oil and regular service, by 100k+ 10w40 semi will fill the void ,still lubricate ,and because it is semi,it will not seap past worn seals as easy as P155 oil. contains a lot less additives and
 detergents and will not clean the baked on sludge ,blocking the pick up . if the astra owners club forum is still going  :-\ look at the posts , many many posts say"just brought an astra ,serviced it with 5w30 ,now it smokes and uses loads of oil "

If you remember me saying about an astra i took on that had been flushed and had 5w30 to reduce emissions ,that loosened so much sludge it blocked the oil control rings .

Do bear in mind that bathroom sealants give off acetic acid when curing - and this kills lambda sensors!
Also - can you be sure it'll withstand the temperatures inside an engine, and not break up and clog the oil pickup strainer? (for consequences, see above) ::)

No joking apart I personally wouldn't use bathroom or clear silicone, but would use a branded purpose made sealant like Hylomar, Loctite etc which are readily available from any decent car accessory shop and much cheaper than the VX goo's.  :y

Exactly, a sump isn't a critical application.


What is important, whatever product you use, is not to over do it. Lots of goo oozing out of the joint shows that you used far too much, and were too bloody lazy to wipe it off before it set! The inner joint will be as bad, and the extra there has the potential of breaking off and contaminating the engine.


I find the acetic acid and lambda sensor comment a little odd, as the fitting instructions for every cat I've fitted specifically recommended the use of silicone sealants instead of exhaust paste. And again, we're only talking about a smear of the stuff that will have gone off by the time you actually start the engine.


I suggest clear because it's good for high temp areas like exhausts, but tend to use black everywhere else because it looks better.

Grey goo is the official stuff for the job... it's a different compound to the black goo used at the top of the engine.

Obviously use what you will, but be mindful of the fact that it will require adhesive properties as much as sealant ones  ;)

I had not noticed that. It's not a rag stuffed there by me. I began to clean the sump and the baffle plate. then it got dark. The car drove home well enough from Ringwood on Tuesday, so I hope it will give useful service. I have not inspected the bottom of the block, just photographed it. I have ordered the sump gasket goo, a new cat to downpipe gasket, and some proper 10W40 oil.

Unlike the 04 Astra, this engine does not have a proper strainer. There is a cast in pipe from the bottom of the sump to the oil pump hole, and the baffle plate is shaped at the bottom so that it restricts input to the pump pipe.

chistopherjohn, ebay vendor of the  GM gasket compound, tells me he has stock but it's beyond use by date, hence his cancelling my order. As Nick says, any old gasket compound should be able to contains hot sump oil under virtually no pressure. In the morning I shall pop down to Halfords to buy a £7 tube of Loctite 5980. I want to get on with this job.

An ebay seller making excuses not to send what your ordered? Surely not.

FFS, ebay is full of wannabes without the capability or backing to be as useful as a used condom smeared in dogshite.  The place is best avoided at all costs.

Today I refitted the sump, having applied Loctite 5990 to the sump sealing surface. I did not apply any to he bottom of the block. I see in Haynes he recommends applying sealant to the oil pump and main bearing caps before the sump is refitted. Does this matter? Should I dismantle again and do it?

The oil pick up casting might have been prudent...

Thanks. I recall Dave the Builder stating that the oil pump sucks oil up from the sump, so if the seal between sump and pump input is not good then pump can suck air, not oil. I could not see the point of sealant around the main bering cap joints though.
I'll do it again.

I think they are talking about the gaps in the gasket surface where the oil pump meets the block, and where the extended section of the rear bearing cap which holds the rear crank seal meets the block.

Obviously there's no requirement for sealant on the other main bearing caps.

yes it is vital to form a good seal around the oil pump pick up part of the mating surface,
but do not use too much anywhere ,you need a seal but not get big snot balls of sealant getting in the oil ways

i just put a thin continuous bead on both surfaces  and smear it with my finger ,removing any excess  :y getting everything very clean ,including your smearing finger first (de-grease with brake clean)
also need a good seal when you put the exhaust back ,or you will suck air and get lambda codes ,eml etc  :y

You are the old Astra expert, Dave. What oil should I put in tomorrow, TC5W/30, TC5W40, or TC10W40. Mileage is 110,000.

I'm no expert ,just had lots of astras to fix and take care of  ;D
now you have removed the sludge ,using thinner oil should not cause your previous sludge blocking the pick up problem , and if it runs fine (not smoking,leaking past seals,low oil pressure light,etc then 5w30 should be ok  :y
I would use the TC 10w40 at 110k with 5k or yearly(which ever is soonest) oil and filter changes but that's just my opinion
open the question up to anyone who has an opinion  :y

Mine's still fine with 5W30 after 112K. I normally look for seepage, signs of heavy breathing and rattliness around the top end, then i'd change to 10W40. I'd stick with changes every 5K, I always flush mine every time as well and the magnetic pick up on the sump comes out clean as a whistle every time.

TC 10W40 might become harder to get over time but it's not a problem at the moment.

Indeed. Last time I thought I had bought 10W40 from Drive Vauxhall Philips March, when I got it home I found it was 5W40, and more expensive. I bought 20 litres of VTC 10W40 this week online for £47 delivered inc. VAT, much better.

That sounds too expensive for 10w40 semi, which should be about £24.99 delivered


Tunnie - yours was the last I got, do you still have invoice for oil?

My mistake, I paid £37.99, not £47, for 20 litres TC 10W40. Still more than TB's price though.

Not all dealers are on TC, but a lot more are than 3 or 4 years ago following a big TC shake up.

No big company will offer discount for cash now, as paying the clearing fee for a card is ultimately cheaper than having the hassles and costs of cash.  Small one man band places might, if you don't need receipts or for it to go through their books.
