The hole is under sized and that is what compresses the bearing, I can't find any one around here to hone it out any. I've done had it rebuilt 3 times and I can't afford to do it again. He put and under sized bearing in it last time and I thought it was fixed untill I got it back in and running. I haven't been able to find another block around here are I would have built another engine. I know some lifters pump up more oil than others I just need to find out which ones is the best.It runs all right long as the lifters are oiling the valves
If your talking the cam being to tight we use a old cam
with grooves cut in the bearing locations to size the bearing..
put it in and turn it so it cuts the bearings that are tight
