URGENT oil pressure stop engine

[Pesky jones]

Firstly, I appologise for another post without any progress, but I cant do anything until I receive the long reach anyway  But someone at work has said the big ends could have bent. I didn’t think I could remove the oil pump unit to reveal the big ends because the bolts aren’t reusable and apparently cost 600£! Im hoping that the big ends never lost oil pressure if it was just the tensioner exploding and loosing oil pressure there. There would still be oil pressure in the block, right? I’d hate to get the head rebuilt/replaced etc spend a load of money only to find there are issues with the block.

Tell your mate that April fools day is next month. 

So the big ends are probably fine?

Cover comes off tonight so will report back/post pics tonight.

On another note, I saw in dazzas thread you said that the laser cam locking tool isn't strong enough to hold the exhaust cam whilst undoing the adjustor bolt? If I need to undo mine will this be a problem?

This tool has been used 6 times now with no problems.

@Roadrebel if it had skipped a few teeth then id agree possibly no valves damaged, but it looks like its skipped quite a bit. I still need to remove the cover to look at the condition of thr tensioner and chain etc. To confirm that was the reason for the low oil pressure message. If its in good condition then the oil pressure message has come from somewhere else.

So the inlet camshaft does still turn when you turn the engine by hand? If it does and the chain has slipped a lot then many valves could be bent. I would start looking for a replacement head.

Let's get the cover off and see what you find - if you thought the rear caliper carrier bolt was tight,wait till you meet the bolt item 7.

Haha @doylebros in my defence I could only get at it with a smallish ratchet spanner. Now I have something nearly four times the length so thats four times the moment, should be enough force. Famous last words.

Chain snapped.

@peskyjones, my car skipped two teeth and that was the cause to obtain the code p0011 and the low pressure message fail the solution was;  two of the Oil lines on bottom of the block ( one in each cylinder ) were blocked

Chain snapped.

Nice.  At least we know what happened now.

[doylebros]

Firstly have you located the broken bits off the chain before you get distracted?

What's your game plan now Pesky?

[dazza]

I feel for you Pesky i know you've asked a few times about the camchain and i think it was on your to do list.

Well done on tracking down the problem.

[Pesky jones]

Ive made a video to explain everything as it will be easier to show what the situation is, but its taking an,age to upload.

 In the cover I found one part of the broken chain, couldn't find the other bit so its lost somewhere. I also found bits of the broken tensioner.

The tensioner had a few bits snapped off and was completely loose, I dont know if you can see in the photo but its lopsided. When you push it down oil seeps out around the seal, so this might explain the oil oressure message.

When I tried turning the inlet cam it would turn slowly, and then suddenly "snap" round with a load of force. Doesnt feel right at all.

Yeah dazza youre right it was in my do to list  should have trusted my instinct and done it asap.

Il upload the video as soon as its done

Now comes the decision time  - price of his engine  http://www.mk5golfgti.co.uk/forum/index.php/topic,105134.0.html and what needs done to it or Get an idea of a cylinder head price http://www.cylinderheads.co.uk

Wow that sucks :( at least you know you were right about the chain slipping/snapping.

[Pesky jones]

Yep that is a small consolation lol

Judging by the state of the tensioner, can anyone tell me if that would explain the oil pressure message on the dash?

What do people make of the turning action of the inlet camshaft?
