For anyone wandering about my earlier email, here's the scoop...
I removed the head and the problematic valve. The cause of the
sticking was a burr on the shaft of the valve that appears to be
caused by heat friction. I replaced the valve with a new one I had in
the parts bin and all appears well. However, I am concerned about the
cause of the burr. The head is one I installed about 3,000 miles ago,
so the problem could have started prior to my use. Prior to this head,
I ran about 30,000 miles on the old one. It failed due to some shoddy
work by the machinist who installed new valve seats - initially, the
seat fell out but on close inspection, I discovered that all the
valves were ground too thin.
Question, how much oil should be squirting out of the holes in the top
of the rockers? I am running about 40lbs pressure when hot. I am not
running a thermostat so the engine stays fairly cool.
