GordonC,
Thanks for the reply.
I dont agree with you however.
Firstly, I understand this is a RS4 topic, but the problem is not unique to RS4 engines. There are numerous examples on the web of RS4s, A4s, TTs with oil deposits covering the intake valves.
What I am suggesting to you is yes...
Hi All,
I know this is an old thread.. but wanted to contribute. I am from Australia and own an Audi A4 2005.
This issue is definitely caused by oil ingestion through the intake manifold via the PCV system. It doesn't matter what oil you use. Ive owned numerous cars (all port injected though)...
