valve cover - oil pooling

[CDeutsch]

I asked that because my oil pool was caused by excesive crankcase pressure caused by too high compression, but that's not a likely cause for most people.

Did you pull your spark plug wires and make sure you could see a ring of black gasket in each whole where the valve cover meets the head? Those gaskeets like to fall off when putting the valve cover on.

Double check for cracks, clean up the cover, and then take it for a "short" drive. That way you may be able to determine where the oil is originating from before it spreads everywhere.
