Just changed my oil and there was definatly gas in it. Was thin, smelly, and could see it on top of the oil. Really starting to think I have an injector that has gone and the other 3 cylinders are overloading with gas to compensate the lack of fuel in the 1 cylinder.

Compression with the engine warm, not full operating temp, was 138 across.
I read that service limit was 122. I know 138 is low and not where I want it, as 150, 160 is. Would that be low enough for major blowby?
