I did a leakdown test last nite. I can't tell a damn thing about the valve guides because the valves are seated.
Compression is 160psi on average and the leakdown (done while engine was cold)suggests the the leakage is not bad. According to the info I have, up to 40% is "normal". most cylinders are running about 25%.
But why do I have the
oil deposits on the top of the intake valves?
