If the push rod is shoter than the correct one per say can it not be adjusted by the rocker?I'm starting to think there to short and it doesnt push the lifter down far enought to get oil in to it.? because looking at the lifter you sure have to push it down far to get it to see the oil hole.make sense?the motor had been o ringed before he said( engine builder) and looked like some had tapped some holes, he put the plug where they were.cold 70 psi warms up 25 at idle and rev up and it goes upto 60psi. I was hoping to go to the NATS this week end with it.any help. thanks phil
