So, I'm at a campsite (Nr Brean, Somerset) a fair way from home in Oxfordshire, and for the first time ever, the oil light comes on, and stays on.
Journey down here was fine, but 1 mile out from site this morning, on comes the light. Pulled over and checked level, plenty. Top end starting to rattle a bit.
Nip back to site gently and call AA. Local garage dude comes out and reckons the oil pump pickup must be blocked. I don't have Relay cover, and I don't fancy entrusting it to a local garage, so...
I 'nipped' home on the train, coming back with loads of tools, oil, filters etc in my car. Got a sump baffle/gasket hopefully coming in to Weston Super-Mare Vx in the morning.
Who's had the single-piece steel sump off an X20XEV, and do you really have to lift the engine off its mounts to do so?
Will I be able to get it off 'enough' without shifting the engine, to see the pickup pipe, and clear it if blocked?
What's the chances it isn't the pickup blocked, and if so what else could be the prob?
All help gratefully received. :y Anyone local? ;)

No experience with that engine sadly, anyone?

Maybe add urgent to the title?

Well, the rattle confirms there is an oil pressure problem so that rules out the switch. Could be a blocked pickup strainer or a stuck pressure relief valve, IMHO. Sometimes you can get at the relief valve from externally (under a plug on the oil pump casting normally). Not familiar enough with the 4 pot to offer much more advice, I'm afraid.

I am just wondering if there is any way to "Backflush the pump/pickup. Then you could just do a simple oil change. Perhaps you could tap into a sensor fitting . . . ::) Just thinking aloud, any thoughts?

Abiton, PM sent :y
-
I am in Bristol, if you require any tools that you dont have, or just need a helping hand, give me a shout (I'll PM you my number now) and I'll pop down to you. All I ask is that you cover the petrol :y
I'm available Sat daytime and all day Sunday.

I notice you have a 'Select' My first Mig was a 'Select' estate, great car, bought it at 5 years old and had it for 5 years before replacing it with a gls estate ::) Had I known about oof then, we would still have it.. :(

strainer unlikely to block up as they are quite coarse.
(just noticed the small print on the piccy.worth a noting)

Anyone got a similar type picture for a V6 housing, as I want to check something out.
TIA :y

There are 2 breakers in W-S-M (head for the sea front off the M5 J21 youll see a VX dealer after 2nd Roundabout - Then 3rd roundabout (I think) turn left behind McDonalds / Pizza hut down a grotty track sign posted "Harris & son"... they have about 4 omegas (some 2.2 & some V6) In the far one and 5-6 in the other....

Hi
If you are at the camp site for another week or so, then consider joining another breakdown club with recovery, not the AA or they may smell a rat. I always take out recovery on the basis that if I cannot fix it at the side of the road then neither can a man who is not as familiar with my car as I am!!
For the same reason, I avoid the AA & RAC because they always initially send out a man with a van who looks at the car and then comes to the same conclusion as me, that it cannot be fixed at the side of the road. There is then another hours wait before the recovery truck turns up. Other operations send the recovery truck in the first instance.

Guys, thanks so much for all these helpful replies, and PMs. Will ask at Vx about the pressure-relief valve, and if they have the 'non-sticking' kit.
Should find out in a minute if Vx have the gasket I need.
Wifi on site is flaky, so apologies if I'm not on much.
Some great help already cheers, now could someone do something about this sodding rain? Ta.
:y

Sorry - only have "My Naff Code Reader"... Maybe one of the Tech-2 guys can help ;D

^ ;D
Well someone did, 'cos it stopped about lunchtime, just after I got back from Vx in Weston with my gasket. ;D
Anyway, good news; it lives!
The oil pressure relief valve was my first port of call after topping up to max, and changing the filter (which was quite grotty considering it was only 2-3K since last changed). Easy to remove, accessible without any disassembly, in fact after tapping it with a hammer a couple of times it didn't need any grunt to undo. No fault found, reassembled and tested, no change. :'(
So I started to undo the bits in the way of sump removal, and then the sump screws, no real grief except crud falling into the eyes/hair continually. ::)
Once all the screws were out it was a job to break the seal, but it came away eventually without any drama. Four screws to remove pick-up pipe and there it was, strainer full of crud. I've got a pic or two which I'll post if I can.
Didn't get sump right off, didn't need to, and didn't use the £40 :o baffle/gasket, as the old one seemed fine. I'll do it all properly at home sometime v. soon.
Good clear out of pick-up strainer, reassembly of everything, filled up with oil and start. No oil light! :y
Still a bit tappy, but I feel sure that will go soon, too busy drinking now to take it out for a proper spin...
Thanks again for the fantastic support, you're all lovely people. :y

Here's one of the pics, too much like hard work to do both, and they look much the same:

well done mate!! top marks for not giving in :y! now you just got to find out where the crap came from?

Cheers fella. Best guess, the car was serviced 'minimally' prior to our ownership.
If you think the strainer looks bad, imagine my alarm as I scooped out the best part of a handful of gritty crud from the bottom of the sump.
Anyone with spare time/energy on their hands, with a mig whose sump hasn't been off during their ownership, may wish to do something preventive... ;)

I'm really glad you're back up & running mate, it's made my day! :y :y

to all,
now this may or may not be relevant!! however a few years ago now we at the autobahnstormers had a spate of people complaning about low oil pressure and oil lights on at slow rpms, accompanied by noisy lifters,when sumps were removed they were loads of crud in there and indeed the pickup strainers were vastly reduced in area owing to the amount of crud held there,almost like a tar or thick grease?it usually happened around 100k mark?it was finally pinned down to extended oil changes recommended by vauxhall, (10k) when all members started doing oil changes at 5 or 6 k this fault tended to not happen,looks like the same thing is happening to the v6,s?
-
Years ago, we used drain the oil out of the yank cars, change the filter (£1) and put 5 litres of parfin in, quick start up, nip up to the round about and back and leave over night.
Start up next morning up to the roundabout and back, straight on the ramp and and leave to settle and cool down a bit. Then drop the sump plug and whip the filter off about an hour or 2after the morning run and leave it to drip drain all day.
New filter on, sump plug in, fill up with oil and check levels and for leaks.
Engine was allways sweet.
Used put the parafin under the wheels for burnouts and have some fun when we were bored. ::)
-
Did an oil and filter change on my 2.6 today and was rather startled to find quite large lumps of crud in the bottom of the bowl I drained the sump into :(. The biggest bits only just fitted through the drain hole so I suspect that bigger bits are still lying in the sump >:( >:(
Looking back at the service history
1st service 20687 !
2nd service 58793 :o
3rd service no idea?
4th service 77950
after that the services happen about every 10000 miles
between the 1st & 2nd services it did 38000 miles :'(
Looks like I am going to be dropping the sump very soon to shovel the crud out >:(
-
i have a pick axe if you need it..

Safely home now, no probs on the way. :)
Not even any sign of leaks around the gasket area, though I'll have a better look later.
Engine now super-quiet :y. Possibly the best I've heard it run, though it's hard to remember what something previously sounded like.
Time for some thanks.
The humour about a Tech2 being needed to alter the weather was my first chuckle during this episode. :y
Agemo: not sure whether one could force oil back through the pump towards the strainer, possibly only by rotating the engine the wrong way whilst injecting it somewhere? :-/ I doubt it would have shifted much of the cloggage even if possible, it took the missus's tweezers ( ;D :y) and a LOT of carb cleaner and time to clear it completely. Then it would all still be in the sump, though I suppose some may have come out by dropping the oil.
Tapper888, pic of oil pump was very helpful, ta. Vx parts man had no idea what I was on about with the replacement relief-valve kit, unfortunately I couldn't print your pic out to show him.
Special mention to Broomies Mate for the offer of tools/attendance at the scene. What a star! :y
Special mention to philrich for emailing me proper Vx info about everything to do with oil pumps and sumps. What a star! :y
Some of you may recall me posting about Pela oil extractors recently. I may be adjusting my views. :-/
I wonder if the strainer was already rather clogged from poor early-years servicing, then the Pela tube tapping the bottom of the sump may have dislodged some of the carbon sediment which then got sucked up to obscure the remaining area of the strainer when running. As I've said, there was a fair amount of flaky black crud loose in the bottom of the sump. How much of this might have flowed out with a 'normal' oil change, I really couldn't say. Arguably more than through the Pela pipe, as some of the chunks were quite large, bigger than the I/D of the extractor.
Also in the sump; one M6-ish-sized washer, defo not from my work; will examine and photograph soon. :o
Against this theory is the fact that the last oil change was back in early May, and no problems between then and Friday 13th. :-/
I'm still resolutely unsuperstitious though. ;D
Cheers OOF, scrappage was discussed, not with you lot as allies! :y
