How much oil is there up in the head? is a lot of oil bleeding from the rocker to shaft clearance? how much rocker side clearance? Whats the engine oil pressure? Is the cam grooved for oiling or just the drilled holes? I found by tightening up the rocker side clearance to .008 from .015 made a big difference, it even raised the hot idle oil pressure 5 lbs
Not much oil to the head, at least it doesnt look like much?? No oil is bleeding by the rockers. Side clearance is .012-.025. Cam is not grooved.
Oil pressure is 65 hot.
I had springs on the shaft and went to spacers with different rockers and it made no difference.
