Oil leak!

Got oil build up underneath headers? Seems like its coming out by the spark plug?

Probably your valve cover gasket. The oil is more than likely running down into the plug valley.

I think it was just excess oil from that valley.

Could be one of your valve cover bolts are stripped. I just went through that problem.

I had to tap about 4 new bolts through this rebuild... :eek2:
