Message	I am beyond the point now where it can be any help to continue down that road. EPR states that the cylinders look fine but may be running a little rich. My AFRs are def not too rich but there is def too much oil consumption or blowby or wherever you want to call it. Excessive oil in cylinders can lead to detonation and while I noticed early on that it seemed very det resistant, that later it was less so, I can not pin it on oil in the cylinders, although I don't see what else it could be. Temperatures were rock solid at 185-190 oil and coolant and my AFRs are great.. stoich to mid 11s at boost 18-22 psi depending on 93 or e85 fuel type...
