Ok trying to understand fully before I take head off, if someone can concur with me all good
This is with no1 at tdc. Valves closed. Only other piston high is no4 (288degs rotation?)
I assume that because it only turns over with cam timing slightly retarded (can not advance to be correctly “timed”)then it must be an inlet valve that is damaged protruding down, the rate at which the valve descends when I try to rotate the cam must bring it into contact with piston.
I assume it’s not the exhaust valve as this is coming to it’s seat at this point as I advance.
