Hi all, this is my first post in this forum, what brings me here is a problem with my 2005 Cayenne 3.2 6 cylinder. Some days ago the check coolant light came on and when I check the coolant level I found engine oil in it,  engine have only  86,000 miles on it. I also have a 944 wich once have a similar problem and it was the oil cooler so i decided to remove the oil cooler from the cayenne and then I pressurize it and for my surprise it has no leaks. The Cayenne never have being overheated ,  I refuse to think my problem is the head gasket, it has being always very well  maintained. Any advice will be welcomed. PD, I check Transmission oil and it is ok, no water in it.

The transmission doesn't really connect to the engine. While you might refuse to consider the head gasket - it is always a possibility. Be worth pulling the spark plugs and looking at them and the cylinders. If one is especially clean and carbon free - there is a coolant leak into that cylinder. Good luck with it.
