hey guys, I had my valve cover and cam adjuster seals replaced a month ago after i was told by both an audi dealership, and a performance shop that that was causing my oil leak... well, low and behold, theres something else leaking oil (in the rear of the engine).


any suggestions of things to check next? its an 01 a6 2.7t with 125K

 

Cam seals and plugs would be my next guess.

As mentioned, it could be the cam seals/plugs. Also, did you service, clean or replace the PCV system? I've read that a dirty or plugged PCV system can contribute to leaking seals by allowing excess pressure to build up inside the engine. Newer models have an updated pcv spider hose assembly and a vented oil filler cap to help prevent this. My 01 2.7T has been getting worse lately, so I plan on doing all the mentioned seals very soon, as well as servicing the PCV system and replacing the oil cap with the newer version.
Regards.
