[QUOTE="dfb, post: 122089, member: 11792"] A few questions...Is oil in ALL the cylinders? If no, which ones are oil fouled? Where else is it present, air cleaner, intake manifold? Is crankcase overfilled? This has a pcv valve, is there oil in the hose from the valve to the manifold? I agree it does not sound like a head gasket problem. It would be unusual for something like a valve guide to fail in all 4 cylinders at the same time. If oil is in all 4 holes, i would suspect it is being drawn in through the intake tract. A compression test would be good also after clearing the cylinders excessive oil. Check for overfilled crankcase. [/QUOTE]
