Oh dear! Oil Leak...
22. Apr 2011 at 19:34

Hi Lads. Here's another old oil leak chestnut! New cam covers fitted and gaskets done properly but the oil still leaks from somewhere. Cry

What is around the back of the engine that can still leak? Sad

Could the head be cracked? Shocked

Its the right hand bank of a 2000 xreg 2.5 petrol with 124.000 miles on the clock. The repair bill so far is about £800.....and still dripping. Cry

Any idea's? Undecided

Who fitted them? Could they have caught the D part of the gasket at the back & it's not sitting correctly.
'Right hand bank' as you're sat in the car or looking at it from the front? Right is technically the (UK) driver's side & is the easiest to fit due to being less ~~crap~~ stuff in the way.

Take it that genuine gaskets have been used and not automotive shop copies. Can you see if the half moon part of the gasket is sitting correctly in place, as if it's come slightly adrift when putting back it could be leaking from there.

If you don't feel confident in where you've had the work done (if at a garage), then try pm'ing one of the mechanic's on here who maybe able to help you out. There'll be cheaper and do a better job at getting it right first time Thumbs Up!

Wellung (West Mid's) - though will have to pm me so I can pass on his contact number to you, as not able to get on here at moment, due to computer access issues Roll Eyes

Or there maybe someone closer to you who maybe able to help you out.

Not being funny here or anything. But is he a mate of yours or someone at a local garage you know?
As if you've been charged £800 so far and there's still no cure I'd be suspicious that you're being ripped off Huh

. Sorry but that's how I see it. Roll Eyes

.

Is there anyone else you know that could check down the plug wells to see if there is oil collecting down there, if there is, it may well be the gaskets not sitting right. Take it the cam covers were new and you were advised to get them replacd?

Apr 2011 at 20:00 There is also the possibility of the oil cooler lines coming loose at the cooler if they weren't tightened down properly, or they could have chafed somewhere and made a pinhole. Remember, even the smallest oil leak can make a HUGE mess. Just throwing out some possibilities....I could be very wrong.

Oh sorry, £800 includes new timing belt, tensioner, water pump etc and complete breather clean, not forgetting good old VAT. Shocked

I'ts a long tedious story....and its really getting on my wick now. My fault for buying such a dog... Embarrassed

Not a mate, but I trust him. I've seen the old camcovers. Warped to chuff and one of the mounting bolts stripped out. Had to be re-tapped.
Do the oil cooler pipes go around the back of the engine then? Huh

That's right - there are 2 metal oil pipes running from the oil cooler around and down the back of the passenger side head, and fitting into the side of the block above the oil filter.

It's either those pipes and their fittings, or the cam cover gaskets.
