just bought an 2002 audi s4 6 speed manuel transmittion with about 105 000 miles on it.. timing belt, clutch have been replaced.....not the turbos.. well i had the car on a lift yesterday and noticed heavy amount of oil on top and dripping down from the left turbo, the car runs quiet it pools nice doesn't smoke, but really i'm woried about that oil... right side turbo is clean as a glass. please help its my first audi and first turbo car..

 

sounds like your turbo is about to blow. you should replace it or rebuild it.

 

or could be valve cover gaskets and/or seals.. remove your coolant reservoir, clean the area really good and confirm that it is or isnt your turbo and repair accordingly.

 

I second that.
These cars tend to leak oil from several places.
It could be your turbo but it's most likely something above it instead. (i.e. cam seals or valve cover)
This is especially true if you don't hear any signs of the Turbo Lady singing or
excessive tailpipe smoke.

 

hopefully, cause there are absolutly no signs of whislting and smoking, the car is really quiet, and it pullls...
