When I tore this motor down ther were 2 1/4 20 bolts in the top oil galley I put my hands on them and they were loose.Sitting up about 2 threads.So I removed them and checked depth of the holes there was plenty of clearance to tighten them I thought.
I now have a lifter tapping after it wams up.I was baffled at why they would be loose inside a engine from the factory.This is a fresh rebuild. Before I pull the intake anyone have some suggestions?My next step is to remove the break in oil and put some slick synthetic in it and hope it free's it up.I'm carrying 40 pounds of oil pressure.Could I have blocked the oil passage?I figured if I did that I would have a whole bank tapping.
