At close to 100,000 miles, my trusty A6-2.8 Avant is leaking lots of oil. Yes, the dealer would love to replace all the seals, etc. for $ 5,000. My main source of oil leaking is at the front. When I open the hood, to the right of the radiator, there are a bunch of hoses. This is where the bad leak is coming from. Since I have a lift, it was easy to verify.
Asking around my motorheads group, someone suggested that it was a clogged PVC valve. Any ideas? And can I attempt to do it myself? It looks like it is really cramped in there! Thanks for any help in advance.......Oh, and is there a picture or schematic available anywhere to explain where the PVC valve is?

Hi babar, just went through this on my 2001 2.8 avant, there are excellent diagrams and explanations of the typical oil leaks and the crankcase vent valves hoses etc at www.blauparts.com

Hope yours is easy!
