Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

My 996 engine has a bad mix of oil and water... Before I pull the engine looking for a cracked head Is there anything else that could cause the oil and water to mix ? Specifically I was thinking about the oil cooler... Has anybody been through this problem with an oil cooler ? A Porsche mechanic told me that the 1999 models had problems with the oil Separator but I don't think that it would involve the cooling system ?? any Ideas appreciated I don't want to pull the engine and then find out that I didn't need to

POST 2Original post

AOS (oil Separator) has water running through it. So it is possible to get oil/water contamination. Oil cooler is another possibility. That said many have changed both of the above components with no success. Most common 3.4ltr engine intermix problems is cracked head. Which can be fixed. Intermix/Cracked head repair - Rennlist Discussion Forums Here is one that was the AOS http://rennlist.com/forums/996-forum/713553-2001-996-c2-loads-of-steam-coolant-loss-mayo-in-oil-cap-3.html
