After thinking about this a bit and reading through the archives, I think what I'm going to do is pull the push rod cover again, remove the oil supply tube, and see if blowing compressed air through the fitting above the rear camshaft bearing will solve the problem. I know the tube itself is clear, as is the drilled bolt and the passage through the head. I suppose it's possible I have the wrong head gasket. Is there any way to tell without pulling the head? (Ha-ha).
