Pressure wash the oil off first with a good degreaser. Then, check the valve cover gaskets. Mine were leaking onto the D/S turbo. Does the car smoke when driving it?

Timoshka

thanks for reply.... no it does not smoke,when i started car for first time from long time standing in garage it smoked for few minutes, now with everyday using, it does not smoke at all, but smells little.
i have no idea about how to check gaskets, do you know rougly how much will it cost(i mean mechanic work) no like big fancy services?

Valve covers, chain tensioner gaskets, and rear cam plugs leaking. will leak right onto the turbos, very difficult to see. But always the issue on all 2.8/2.7T engines

what does it mean if the car smokes? thanks.

This talks to all the know oil leaks for the 2.7T motor.

Chances are that it's Cam Chain Tensioner Gaskets and Seals, most common.

There is a link in TechTips:

look for 2.7t Valve Cover and Cam Chain Tensioner Seals.

That shows you the inexpensive way to do the work yourself.

I have heard that the engine air breather system can get plugged up, and the pressure causes oil to leak in many places. just an idea

ECS Tuning-Audi

Unless the car is smoking while driving, producing a dentist's drill noise while accelerating, or lacking power severely the turbos are probably in good working condition.

Valve cover gaskets, cam chain tensioner gaskets, and cam seals all like to leak oil. The oil that seeps out of these leaks down the head and on to the manifolds (which get extremely hot) thus causing some smoking if oil comes in contact with them.

We have complete gasket kits available below!

Let me know if you have any other questions.

its ALWAYS the chain tensioners and cam plugs.

I am sorry to say, but if you are not mechanically inclined, be prepared to be taken for a ride. (figure of speech).

All of us here have had this problem at some point. The parts are not expensive but the labor is. If white smoke is not coming out of the tail pipe then it is probably not the turbos. Diagnose the cam chain gaskets and valley plugs first. Then the turbos last, and definitely not the cat converter or o2 sensors.

Do not let anyone tell you its the cylinder head gasket, you will end up paying for the job and still have the oil leak. Buy the parts as a kit. It will be a cheaper. See blauparts.com

And last. It is a job easier done with the timing belts removed, so replacing the belts and fix the oil leak at the same time will save you hundred(s)
