Only when engine is running and up to temp ive got an oil leak at back of sump. Pretty sure its not rear crank oil seal as this is new, Is it engine out job or can it be done in situ????

 

any advice

Could it be from one of your cam covers, and running down the back of the engine? Very common...

You need to identify what it is first!

if its the rear oil seal pretty sure you can do it with engine in but would need to take off gear box to get at it!

Worth checking the drain plug is nice and tight.

Ive had the car over a pit and cant see any oil anywhere above the sump gasket, and when the car is standing theres no drips, its got to be either rear crank oil seal (which is brand new) or from sump somehere, been told theres some good stuff you can put in the oil to help expand seals so gonna give this a try if not ill just have to yank the engine out again (sigh)

when the oil seal was replaced did they remove the oil seal bracket and replace it like that, or just remove old oil seal and replace? as a new one can still leak if installed incorrectly

tbh I dont think it is the seal??? i seem to have a small oil run on the pass side of the sump, it sits on the level part of teh sump if you know what i mean and only drips after i move the car, its very strange, gonna try this oil additive in my run in oil before I change it in a few weeks and see what fifference that makes, failing that its engine out again :(

Well if the sump is the issue the addative is not going to help as there is no gasket on the sump, the two half moon end seals are hard neoprene so again will not help...shame.

I would use some brake cleaner spray to clean the area, than run the engine to see where is the oil coming from exactly.

Done that but it's very hard to tell

really?? how did you manage that??

hmm might try that might just be easier taking the engine out again.

If you've got non standard turbos you might struggle to get the sump off unless you have an extensive set of tools, one of the bolts hides behind one of the gearbox brackets which in turn hides behind the RHS turbo. I found it to be a PITA even with the engine out!! Presumably you've tried nipping the bolts up a bit tighter in the problem area?

Good luck

Is it definately coming from the where the sump mates with the block? I.e. no oil about the seam?

about = above....

It looks that way, ive had the car over a pit and got a mirror up there and everything above the sump to block seam, is nice and dry and once the car is up to temp you can see a small run of oil coming off the flat section of the sump on the pass side if that makes sense, Im thinking of whipping the gearbox off at the weekend and having a good look, if its something I can fix with box off then great if engine has to come out im half way there anyway.
