Title: Omega 24v Work in Progress
Post by: grifter on 25 November 2016, 11:29:28
Hi

Decided to start a work log of things I am doing/planning to do on my recently acquired 'meega. I have a word doc as well with all work needing done, parts required, things to check and anything else that crops up.

My list of parts required/things to do so far are:

Service Items:


Suspension parts:

Other parts required:

Things to check/do:


If you see anything I might have forgotten then I can add it to the list.

Let the battle commence!

Hi Grifter

GOOD LUCK ON THE BATTLEFIELD!!!

Did you look seriously after rust? Ommis have many hidden places  :o

Last year I thought i knew them all, but that was before I rebuilt my sedan.

Hi Rolf

As of yet I haven't went into the bowels of the ship although I have checked as much as is practicably possible without stripping things off. From what I see things look quite good. I can't see anything untoward and judging by the condition of the bits I can see it looks to be fine. However not being complacent I will be going round it in due course with a finer toothcomb aka torch and screwdriver!

Cheers

Andrew

Picked up the battleship tonight (for some reason there is a battle ship theme going on - that I started!) and got straight home as didn't want a fuzz tug with those tyres. On the way I could defo feel the steering was a bit twitchy and almost a bit floaty at times. I kept distance as didn't want to do any sort of hard braking or steering as I wasn't familiar with handling, especially with it being flippin cold as buggary here and the roads all slimy with grit. Also noticed steering wheel on dead centre the car veers slightly to right.

Once it was on my driveway I went out with my trusty head torch and started having a bit more of a look around. Started with a bit of a hose down of the bottom half to get all the grit off. Cleaned out under arches, checked in behind rubber trim on bottom of back door for corrosion etc. Gave those bits a spray of acf 50 anti-rust. Also gave the wiper pivots and the spindle threads a little spray oil, plus door hinges & latches.

Then had a bit of a poke about the engine again. Checked oil etc. Was going to brave checking throttle bodies but didn't want to push my luck lol! Didn't want to start something I couldn't be bothered finishing, especially at silly o clock.

There is a bit of oil stain on sump guard just under front of engine. I did notice this before but had a bit more of a look at it. Obviously need to clean it up first before seeing where it might be coming from. Crank seal, sump seal? I think someone mentioned it's worth taking oil pan off to check oil pick up is clear.

Next step was the boot. I noticed it was a wee bit damp. No leaks or wet carpets, just beads of water on the inner wings and up underneath each side of parcel shelf. Gave this a wipe down, removed spare, cleaned out usual crud you find down there, bits of paper and crumbs. Tidied up first aid kit and tool box compartment bits, securing them up with the rubber strap thing. Will get dehum in there soon anyway as most cars end up damp inside due to cold/wet weather here so worth a good dry out now and again.

That was me done for the night. Next step will be front up in the air and have a look around underneath.

Had a more in depth look at the oil stain last night. It seems concentrated on the passenger side and seems to go up to the rocker cover area. I'm assuming that is the problem. Looks like a pig to change with all the stuff running over the top of it. Had a look at the other side and while it is not oil damp down the side it looks like the rocker gasket is sweating a little.

Also checked battery terminals, + one was slightly loose due to not being pushed right home on the post so loosened it, wiggled it back and forth then pushed it in  ;D home and dry, and not loose now.

Next thing I had a bit more of a look at was the coolant. It is up to level however I kind of thought it looked a bit "red" perhaps stop leak I don't know, or something else? I will be flushing it all as a matter of course, but will be doing a head gasket test before I drain it. I also noticed that the plenum chamber thingy must have been off at some point before as one of the little plastic covers was missing off it.

Finally I found some service history in the big wallet thing in the glovebox. It has service history up to 55k. I noticed at 30k and about 55k it said that the toothed belt (including tensioner on first one) had been changed. I take it this meant the timing belt. Will need to have a look again as it might be that it had reached the X amount of years for timing belt change rather than based on mileage as a change at 30 then 50k is quite a short mileage range between which to change the belt.

Car was originally registered in Luton Beds and looks like it spent it's first 40k down there.

Managed to get a look at the bushes on front. They seem a tad worn out, and they look a bit goosed on top. I also tried a big screwdriver between the subframe and arm and there is about 4mm of free play before any resistance is felt.

Also took measurements on Drivers side with spirit level. Difference between top and bottom of wheel is about 3/4 of an inch inwards at top. Seems quite a bit but don't have a baseline of what it should be?

Everything else looks ok. I did notice that on full lock there is a bit of play, or what feels like play. I have the same thing on my senator, no play until you get to full lock there is a bit of movement back and forth. Wonder if this is "to be expected" on a steering box?

If replacing cam cover gaskets[which it sounds like you may need to do]make sure you clean the engine breathers thoroughly too or they'll just leak again!

Ok, so here's a few snappies of some of the checks I Made at the weekend.

Can't remember what side this is but it doesn't look as bad as the other bush, which is looking like it has lifted out it's bonding.

(http://i132.photobucket.com/albums/q11/Pichost28/Cars/Omega/omega-NS-inner-wishbone-bush_zpswyjlqqvp.jpg) (http://s132.photobucket.com/user/Pichost28/media/Cars/Omega/omega-NS-inner-wishbone-bush_zpswyjlqqvp.jpg.html)

New tyres anyone?

This is the bush that looks like it is popping out the bonding bit. Looks different to other one, which doesn't look as bad.

The angle here looks more than it actually was. Although 3/4" of neg camber seems a wee bitty much.

1deg10sec seems to work well for OOF members who have managed to get it set accurately.

3/4" (say 20mm) is way too much. I think I worked out that on 17" rims I needed 8mm (measured at the rim) (not much point trying to measure off the tyre).

I can't imagine worn back arm bushes giving this amount of negative camber though I could be wrong. I've checked everything else and it seems fine for wear. As it has only 77K on it I can't imagine it's had any major front end work on the struts or steering, although again I could be wrong.

Totally agree though 3.4 is way too much of a difference between top and bottom. Will need to get bushes changed and geo done.

Each front hub/axle is bolted to the McPherson strut using two bolts. One of the bolt holes is slotted to allow adjustment.

Wear in the bushes will allow some movement but it is failure to adjust the camber using these bolts which is the cause of that much camber.

Same as the Senator. In short term I will likely have a go at setting it up using the socket spacer method I've seen on here. Mainly to get it over the winter months, and minimise wear, when I won't be using it much anyway. Timing belt is the first and most important thing I need to change.

Title: Re: Omega 24v Work in Progress
Post by: grifter on 18 December 2016, 21:59:25
Can anyone recommend where to get the poly bushes for front of arms? Super flex perhaps, or is there a recommended one for the omega?

I've also priced up some more bits

Timing belt kit  GM only £120 inc vat
Water pump  GM £80.46 inc vat
Fuel filter  GM £7.19 inc vat
Rocker gasket --  GM £27.28 each
Sump gasket  -- GM £11.70 inc vat
Sump sealant – Dirko £7.14 inc vat

Total - 253.77

Want to get belt changed first then buy up the suspension bits as and when I can afford them.

I am pretty certain that I used Powerflex https://www.powerflex.co.uk/road-series/product-details/Front+Wishbone+Front+Bush/1760.html (https://www.powerflex.co.uk/road-series/product-details/Front+Wishbone+Front+Bush/1760.html).

I definitely bought them from ECP - mainly because ECP were the nearest to me who claimed to be distributors.

ECP were pretty rubbish though. I went in and ordered a pair. ECP said they might be about 4 days & took my phone number. I rang after a week to see what was happening to be told that because I hadn't been in and collected them they had been returned :-X they turned up in the end though and work well.

I think the colour is officially called Ural Mountain and the code if I'm not mistaken is L382. I couldn't see the "L" on the VIN plate just the number 382, which matches up to a number on the colour chart so assume that's the colour name.

Cleaned out air intakes today, not a total strip down but a spray with WD and a wipe with a rag. Quite a bit of "mayonnaise" caught in the little rubber springs in intake pipes. All I need now is some tuna!

Replaced little vac pipe that goes from servo 3 way valve to.....somewhere!

Noticed a thin earth cable, with large round washer type connector, and 13mm nut to secure up the back of the tank mount, gave it a wee scoosh with WD, loosened and then tightened (as you do) it just to make sure Earth was still clean enough. Also noticed some rust starting on the back chassis legs. Will attend to soon enough.

Took it for a spin :)

Today's job was remove both front wishbones and start ripping out the bushes. I had a bit of a wobble when I discovered the quite inaccessible rear bolt and posted up here with some details:

http://www.omegaowners.com/forum/index.php?topic=138465.msg1783317#msg1783317

Needless to say I got all this sorted and the only thing I need to do now is hack saw out the old bush collar for the front bush and stick the poly bushes in and rebuild. Got the new ones in for the rear bushes.

Also while under there I took a few pics of the light oil leak in sump area and also the old bushes. So here we are:

Is it sump seal or plug leak I wonder?

Oil leak probably a combination of front crank seal, rear crank seal and cam seals looking at the location of the oil on the front sump lip, sides and bell housing.

I do know the cam cover seals are sweating, especially the N/S one. I'm going to clean the oil off and see if it is leaking from anywhere specific underneath. It's doesn't seem too dramatic - yet! If crank seal will change when I get round to doing belt.

The rear one will require you to separate the gearbox. Usually if you have oil dripping from those two bolts it's the rear crank seal.

Physically fit ahem! Actually not bad just a lazy git lol. I did change the gbox on my mk2 granada myself on the deck so should be able this no problem. That'll be a job for later.

work update:

Both front arms cleaned and painted with zinc 182 then halfords gloss black paint; waiting for that to dry. New rear bushes in place, just the polys to put in tomorrow and stick em back on.

And being an auto, the box is bastid heavy.

The Omega manual weighs about half an AR25 and twice a Type 9... you wouldn't even have been trying if the Granada hadn't been on the ground... clutch and box change is twenty minutes with a ramp ;D

Hi grifter

Good job! I did it last summer on my Caravan.

I used new wishbones, removed the painting and did it new. Base was a 2K epoxy zinc primer, designed for boat coating in salt water. This is normally not available here deep down southwest, a friend sent it to me from the northern coast.

I see your logic as the paint on the new ones is never that good, just a flash of black paint, they just rust away within a year or so.

Post by: grifter on 04 February 2017, 23:09:08
So ventured out and got the wishbones back on today with new polybushes. Bit of a faff getting the arm in at first. Realised I had to take off the roll bar link pin on both side and push the bar up out the way. Luckily the links came off easlil as I think they've been replaced recently so were seized up.

The other bits that were a pain were relocating the nut back in the subframe for back bolt. Passenger side seems more confined to get at. After tightening up the bolt, the socket seemed to get stuck on the nut in the subframe and I couldn't get it off for a while. Luckily there is an access hole in the side of subframe I could see the socket through so whacked it a few times with a screwdriver hammer combo and it loosened it off the nut enough for me to "octupus" my arm in and round the sub to lift it out.

Next bit giving me grief was getting the ball joint back in under the steering knuckle. I utilised the strong bar through the hole in the arm and levered it down as far as I could until it hit out on the subframe.

At this point there seemed to be still a couple of mils still to go but putting the balljoint stub at an angle was just enough to catch under the end of the knuckle with some brute force pushing down on leverage bar for the wishbone. I then had to quite violently shove the knuckle forward so it popped into place. This has to be done with the steering in straight ahead position. It won't work at an angle.

When I was putting the WB back in I devised a way to hold the strut back out of the way so I could feed in the WB easily. As you can see from the pic below I put a strong bar in between the brake caliper bolts, shoved it back out the way and then held strong bar in place with the side of my leg. P.S, this only works if you have thighs that will crack walnuts!

Now from looking at the wheels they do appear to be a little less tilted in at the top although measuring with the spirit level and gap difference between top and bottom of wheel still seems much the same. I didn't think the bushes would make much difference here as it looks like the camber does need significant mechanical adjustment still.

Yes will be getting another pair of work trousers soon :)

While I had it up on stilts also cleaned off the sump of oil and around that area. Had a look at the exhaust as well as it is blowing forom back end and the front sections look well past it too. Looks like will need a whole new system in the not too distant. Back section has been extensively cowboyed up with some sort of metal wire and exhaust repair tape or whatever it is.

The wishbone rear bolts really should be fitted so that they hang down through the subframe, not be pushed upwards. Which is easier than trying to fit the nuts on the top.


Fitting the struts back onto the balljoints requires a good heave on the wishbones: I wedge the jackhandle in there and sit on it to leave both hands free to wrestle the strut into place. I will be doing this job on mine later, as I've got new springs to fit.


One of the reasons to change everything in one go is that it is much easier to fit the wishbones, then the hub carrier, then hang the strut from its top bolt and finally fit the camber bolts.

Hi grifter

As Nick said, do not fit the bolts from downwards! I had the problem last summer. Someone did so and it was hard work to get the bolts out, because the rubber bearing in the WB was broken and it was impossible to screw the bolt out. So I had to use "special tools" to bring the bolts out downwards

I know I don't know why I put it back in like that tbh, plus I'm assuming that it wasn't fitted like that as standard. That on top of DG saying about the Ball joint I think might put it back on the stilts and change bolt round, plus renew the Ball joints.

Is it easy enough to feed the bolts in from above as it is hard enough to get in there and get the nuts in to the aperture. When socket is on the nut it feels like it is at an angle in towards chassis so thought it would be tight or impossible to feed the long bolt in. I thought maybe this was why it is fitted like that as the bolt couldn't be fed in from the top.

Bolts are fitted from the top at the factory and very deliberately...

If the nut becomes loose, the arm stays put... upside down, if the nut comes loose, the bolt drops out and you're dead.

Noticed a couple of things recently, looking for thoughts/suggestions on these:

1) Temp seems to hover around the first bar on the temp gauge, sometimes goes up a bit then back down. Thinking this should be up a bit higher? Stat likely or is this normal on meg facelift v6

2) Occasionally when pulling away the box appears to change like it is in sport mode, holds first a lot longer etc. seemed to be when cold it does it. I'll look for a guide on here for checking slushbox fluid, however is this a common one or pointing to something else to check?

3) Ventilation overall seems a bit shit, trying to get used to not having a normal spinny heat dial with fan off-1-2-3-4  switch. The blast onto the screen seems pretty poor with just pressing the fan speed button up, only top bars provided anything like a semi-sufficient air flow, I press that front screen clear thing and it then blast quite the thing, but air is cold at first start so not going to clear and it just keeps engine cool, so turn it down a bit and let it warm. There's not any dampness in the interior or boot, just seems to be poorly ventilated and front screen usually mists up. Is it maybe the pollen filter blocked? I couldn't believe outside temp sensor has a bearing on climate control so need to get that fixed too, maybe that part of problem.

I've never heard of the transfer pipe, is that something that goes faulty or something? Can the o ring be missing in some cases. I guess if someone had been in there maybe they left it out.

...and depending on the age of the car, the thermostat could be one of two styles - the older style utilises longer bolts and IIRC a round profile O ring, the newer style utilises shorter bolts (or packing out with washers) and squarer profile O ring with a couple of notches to hold it in situ while you fit it.  :y

Transfer pipe as per post above - there's a chance you'll be able to remove it without any damage, but even if you do, you'll still need two new O rings to be able to re-use it.

It is a thin walled aluminium casting.  Corrosion causes pitting of the tube as well as weakening it.

The end with the o rings on tends to seize in the thermostat housing and it is normal for the tube to break when you are fighting to free it.

Today was alignment day and everything on the face of it seemed ok, the only adjustment was toe needed set. Camber was within limits. The techy had to heat the adjusters though. He left it to cool off before actually setting the toe. You could actually see the setting change as it was heated and then left to cool off. He did say is this got sport suspension as it looked low at the front. And was it the one with adjustable rear shocks, said not afaik, think it is elite one that has those.

Glad that's that out of the way. I'll keep an eye on the tyre wear as I have been doing anyway. It's looked ok since I got the tyres a couple of months ago at the same time bushes were replaced on arms.

Today I started stripping the gubbins off to get at the Timing belt. Everything went pretty much ok apart from a slightly seized on power steering pump pulley, a bit of fannying about to get the top cover off, in the midst's of which I decided to break a little sensor at the top right hand corner whilst removing it.

Now that I can see in the belt area it looks like it's due a change as there is a lot of rubber "powder" sitting atop the timing belt bolt mount in between the 2 cam sprockets. Nice little confirmation tell tale for a belt change if you ask me, except of course for the more dramatic option of a snapped belt!

Did you get a print out? The 'limits' generally used by the trade allow too much camber & hence result in excessive wear on the inside edge of the front tyres. :(

I don't think the belt ever fails - it is always a tensioner that lets go and lets the belt fall off the sprockets :-\

You need a replacement vacuum solenoid. The one you have broken controls a flap at the rear of the intake manifold that will have a noticeable effect on the engines tractability.

No, I forgot to ask damn! Actually thinking on it I think he might have used an omega 4 pot setting. I remember watching him scroll through the options and seen this as the last thing on the screen, he kept asking what model it was. Tbh I wasn't convinced it was done correctly as it seemed like he was too quick to say everything else is in tolerance it's just the toe that's out. He said he'd done one of these a few weeks ago then said no wait it was a carlton. The only way I would be sure is to do it myself!

I had another look at it, there is bits of belt rubber all over the top of the water pump recesses and all over the back of the cover, not just dust, but bits of rubber too. The teeth look quite thin on the skin.

Bit of an update on progress. I've now finally got a working crank lock and have got to the stage the belt is removed, water pump is removed and have started stripping out the rest of the gubbins up top to get into the cam cover gasket. When I was removing the OS coil I noticed when it started to release itself there was a slurping noise, similar to pulling a welly out of mud, I thought "uh oh" or a more choice word, which I will refrain from repeating!; and sure enough the back plug hole was full of oil.

(http://i132.photobucket.com/albums/q11/Pichost28/Cars/Omega/omega-spark-plug-full-oil_zpsya5m3idm.jpg) (http://s132.photobucket.com/user/Pichost28/media/Cars/Omega/omega-spark-plug-full-oil_zpsya5m3idm.jpg.html)

I'vve not noticed any running problems. I just hope that the oil hasn't seeped into the coil. I will proceed with removing the NS one and see how that goes.

As far now this is how the engine bay is looking

Tonight's job was to clean the throttle body up and attach the plastic breather thingy on it. Wasn't too bad inside, just a wipe down with some thinners, check the pipes and internals were clean and rebuild. Relating to my previous post on the rusty coil pack from N/S. I noticed the bolts for rocker and coil pack on that side were rusty, at the back especially.

I also cast my mind back to when I got the car and remember that on some occasions there would be a little kick when on throttle, so rare that you would hardly suspect anything. So maybe the coil pack was starting to get affected by this oil ingress and rustiness.

If it's been left maybe another couple of thousand miles and things would have started to go pete tong.

Also noticed power steering leak up near bottle. Guess I need to tighten the jubilee

Couple of tips now.....a wee trick for soaking oil from the plug holes is to get a bit of kitchen roll, then roll it up like a big joint :)
(just leave out the tobacco and gange) so that it has a hole in the middle where you can put this over the plug, push it into the hole, over the plug and squash the top bit down. Leave overnight and then remove to find most if not all of the oil has soaked into the paper.

Cheech and chong would be proud:

Squashed into plug holes:

Next tip is for easier access to engine. If you have all the air trunking and stuff removed and you are working around the top and at the back of the engine, to get easier access you can actually stand one foot in the front of engine on top of the anti-roll bar, sit your erse on the front panel, and put the other foot on the bumper (over a cloth if you are sensitive about your bumper paint). I found this really helpful for accessing the rocker cover area and cleaning it as well as the breather pipes at the back. If you do this make sure to unclip the crank sensor plug otherwise you risk standing on it as you put your foot in there and breaking the plug off the connection.

Picture of my foot - note I am not affilated with the Nike brand and am not endorsing then in anyway!

Finally starting to build this thing back up now that I've got TB on and am happy with the positioning and tension. The timing and adjustment went not too bad apart from having to readjust the tension back a bit after doing some adjustment on the top idler to pull bank 1 & 2 into line. After that we were good to go. I've also cleaned out the bottom of the engine above the sump, which was caked in crusty oil gunk. Plugs are back in and Left side cam cover is back on with new securing screws seals included.

Here you can see how much extra tension I ended up with after adjusting the top idler, this is now back on the outer notch where it should be for a new belt.

Not far away now. Tonight's job was to torque down the inlet manifold bridge, put timing cover and pulleys on, put the injector plugs back in, put aux belt on, coil packs in and tidy up the wiring and tubes at the back of engine. Initially when I was putting timing cover on, I tried rotating engine and it was scuffing at the top left. Took it back off a bit and jiggled it about, tried rotating it and then it was fine. Tightened back up, turned engine and jobs a good un.

Spent a bit of time tidying the wiring/vac/water pipes up, they weren't too bad, for a start there is a what looks like a water valve at the back, this was sitting off the big clip that holds it in place. Routed wires and vac/oil pipes so they weren't chaffing and were secure as they could be. When I put aux belt on I felt as if it was ever so slightly on the tight side, the tensioner was right back and the belt had to be pushed over the pump, not with great force just light pressure.

Final steps:

put plenum on
Put filler cap on
Put wiring trays on
Put air trunking in
Put water hoses on
Fix power steering leak at bottle
Oh and eh fill with water and oil before trying to start....and check rad drain is shut first!

Getting all excited now  :)

What a ball ache it is putting on that plenum and all wiring and tubes! I did spend the time though to make sure everything was routed as securely and in the proper places. There is a wiring securing fastener to the right of the clamp on the air con pipe just at front of engine. I can't see what it is that goes through here, there isn't any wiring or anything that goes near it, unless it is that part of the loom that is reaching across the right hand cam area. It would be a bit of a stretch to get it round that, I'm not sure but will check tomorrow. Also cleaned and tightened up the slight weep at the power steering bottle. The pipe clamp was quite loose.

So I've got to a point where the only thing left is put on inlet manifold pipes, radiator hose, change oil filter, fill with oil/water and give it a whirl.

Tonight was the big night. I had my teeth gritted when starting it, but was confident as I had taken so much care (hammers and swearing) to rebuild the thing.

So before I done that it was change the oil filter, put the bellows on, reroute one of the cables along the cable tray, fill with oil and water, then connect battery and go for it.

On first flick of the key I heard a phut phut like it started but only firing on one or two pots, thinking ok there is no fuel pressure etc. need to give it time to build. Restarted and clatter clatter it went up to about 2k rpm, usual dry top end when all the oil has drained out, spent what seemed like eternity increasingly gritting my teeth as it went clatter clatter from top end. Then after about 5 secs (what seemed like an hour) it started quietening down.

Then I noticed the idle surge a bit, only by say 500 rpm once or twice then as it started warming up the engine really settled down and was very nice and smooth, except of course i couldn't enjoy it because of the farty blown exhaust.

So something that I noticed after 5 or so mins the cooling fans came on, reckoned just air locks, trapped heat, and as I was topping up with coolant/water I had to go through that cycle of fill it, let it drain, let it spew up a bit, let it settle, fill up, you get the idea. Then the big fan on the front left of the rad came on, the engine started cooling and the water level went back down. Long and short of it, I got a full bottle of Anti-Freeze in with about the same again for water. Says 9.5 litres in the book. Will let it cool off over the next day or so and re-check the level is at KALT!

Once happy with the engine I decided to get under the back, change the fuel filter and pull off the old exhaust bandage to clean and repair the exhaust. Turns out I've no exhaust repair paste, I thought I had, and was going to put this on then one of those aluminium tape repair thingys. I really should be getting a new centre section as the pipe join has seen better days, however I can fashion a repair for now until I get funds to buy new exhaust bits.

So that and a repair to the front light casing securing bit, whichi s cracked, plus an all round MOT check is all that is left now. Thought I'd never see the day! Here's some vids and pics of tonights efforts.

Here is two videos, one of it running, and one of the hole I now have in the exhaust after removing the repair bandage. It sounds better now with that off!

http://vid132.photobucket.com/albums/q11/Pichost28/Cars/Omega/Videos/omega-exhaust-blowing-video_zpsu4migfzp.mp4

And 4 pics of fuel filter and exhaust rot, the first pic of exhaust is actually above the pipe, near driveshaft, the bottom of the pipe is fine. I thought what a strange place to rust, usually the rust at the bottom.

Coolant needs bleeding with the heater temps both set to HI and the blower set to minimum. Initially with cap off then once fans kick in, cap on and recheck when stone cold

Now trying to source headlight drivers side due to broken clips (arrggh VX you and your stupid plastic clips, cavalier all over again!) and ran out of gun gum to patch up the exhaust. Have 2 bandages on it, and one tin of gun gum. Still parping from top. One more bandage and a shovels full of gun gum should do it. Hopefully it stays together long enough to get an MOT!

Whilst under the rear of the motor yesterday I started looking at the doughnut bushes and the edges of them look frayed, i.e. the rubber moulding seems to be peeling off the edges. I don't know if this lends itself to potential sign of worn bushes upstream. I considered mileage, which is not very high but thinking more about the age, then the bushes are likely to be perished where it matters?

I promise I'm not looking for things to replace for the sake of it but wondering about MOT. I am going to put it in for MOT as if I get away with it for now that is fine. If it should fail then I'd likely replace with poly bushes anyway. As I don't have much experience of the "driving feel" of Omegas, closest is senator, I did think the back end was a bit twitchy perhaps. I don't know, maybe it'll help me do doughnuts (excuse the pun)!

Something else I noticed when doing timing belt was the air con pulley had slight play in it. Nothing I'm going to concern myself with just now but noted for future.

All MOT'd now, only advisory was N/S roll bar link rod rubber cover was a bit on it's way out (not the official wording of the advisory). He said when the steering was turned you could see the bush neck open up. So all in all it's running very well so a job well done and time to enjoy the fruits of my labour (copious swearing and keeps saying whoever designed that needs shot).

Only thing left to do is replace the O/S headlamp (whenever Parcelforce decide to drop it off at my local PO), I got away with the light being insecure as the MOT tester tie wrapped it up to get it through, he was a good guy I must say!

Each front hub/axle is bolted to the McPherson strut using two bolts. One of the bolt holes is slotted to allow adjustment.

Wear in the bushes will allow some movement but it is failure to adjust the camber using these bolts which is the cause of that much camber.

Same as the Senator. In short term I will likely have a go at setting it up using the socket spacer method I've seen on here. Mainly to get it over the winter months, and minimise wear, when I won't be using it much anyway. Timing belt is the first and most important thing I need to change.

As an aside, was reading through this thread at work I've done etc. and I remembered I'd checked my cavy (with fixed camber afaik) camber and it was much the same. I'd imagine a wheel should be perpendicular to the road, even a couple of mils out you would think uneven tyre wear but no not really. There must be a reason it is set like this, some mechanical sophisticatory that us mere mortals don't understand.

Small update: fixed scuttle leak. Sealed the join on n/s and sealed wiper hole on o/s with panel sealant. Dried out coil packs, look ok. One got a wee crack at base but no rust. Took plugs out. They were very hard to undo, and 5 of them broke, so got new ones from vx dealer. Due to rebuild it all tonight if it doesn't rain!

Seems to be running ok now, after a kind of noisy start up. Got me worried. It sounded like a tappety noise, maybe sticky tappet. It disappeared then reappeared, but eventually went quiet.

Probably lazy cam followers/tappets.

If it only does it from cold then it might be the exhaust manifold gaskets.

Thinking the same thing. It went away after 5 mins and then when I tapped the throttle a little it came back then went away after a couple of mins. Seems ok now. I did an oil change on it but I don't think I flushed it. Will do that next oil change give it a good flush.
Title: Re: Omega 24v Work in Progress

Next job i think is flush and oil & filter change in box as up change is still a bit sticky. It looks like the same box as in senator if not mistaken, small sump and large sump. If so i d have spare gaskets. Have also started aquiring rear exhaust bits, can only afford one bit a month. Need to get 2 centre sections next.

Still not convinced scuttle is properly sealed, either that or water is leaking in wiper hole to engine bay. Not suffered leak into passenger floor again, checked drain and is clear so would love to know how that water got in. Hopefully it was the little bit of bulkhead join i sealed with grease. There was rust starting in join so i dug out all dried sealant and rust treated it but hadn't sealed it at the time.

Noticed tonight on my drive home the EML was on. Whether filling it with costco fuel made any difference IDK but happened soon after that I'm guessing. Decided as I had chance to get some at the low price I took 20 bucks worth.

Code is reading 0150, which I believe can mean 4 things but all related to the 02 sensor. My exhaust is rotten at the back and needs replaced and again not sure if this is precipitating the problem although this is all after the cats area.

Will need to try and get someone with a code reader or splash out and get one that can clear codes see if they come back.

Wee update to keep things rolling on my WIP. I've been posting various things all over the site but haven't updated anything here, so here we go:

EML light is now out. This came on when I'd filled up with costco fuel, I think this was a big coincidence, however it had me thinking could it really have been that. I came to my senses and thought no it can't be.

So at the same time, or just after this event, I was planning to replace the back end of the exhaust, well the back 2/3s as it was toast, mainly around the join to the tail pipe. I had hoped that maybe this was causing a problem with gas flow and that the code for 02 sensor was on as a result. Idk but a fair assumption at best.

I hadn't done anything else to the motor so I was fishing for other things that could have fired the code off.

Right about that time I also experienced a judder and at one point , a stall, when I was pulling up outside house. This happened a few more times so I was getting edgy now and had lost confidence in the reliability of the car.

This then led me to think that the crank sensor was on the way out as I had read on here so many times, so bought one of those, Gen GM one. I then decided to give the vac pipes and connectors another good look over, and the only thing I could perhaps suspect was the plug going onto the airflow meter bit at the front, which the plug bit that secures it on was broke. However this happened ages ago when I done the timing belt I decided probably not that, as it still felt secure in it place, and had no issues since last year. I got a tie wrap and secured it round the plug then tightened it so it would pull it right into the plug socket.

Immediately after this, the EML light was still on, so I decide maybe it was the exhaust sensor and/or crank sensor etc. I then drove down to my folks to drop off a few things, stopped for fuel on the way and when I restarted it voila the EML light was out!

I had heard that it can take a bit of time for codes to clear, so it must have been this loose connector. Just goes to show the carnage a loose connection can cause. Codes were saying one things but it was that. It also goes to show how that a code doesn't always mean that, and ironically, the code will only be correct if the whole electronic circuit is not breached in any way.

I checked tyres a few days ago as well and they were all around mid to low 20s, so bumped them up to 30, and fuel economy is also much better, and the car is running very sweet.
