Okay so for those of you following my oil pump swap drama, i got all of it back together and still have the problem with the valve noise. The pressure is good now but the valves seem to go "dry" every once and a while and start to clack horribly. It also seems to miss fire constantly just kinda stutters and it gets really worse when the clacking begins, almost to the point it wont run anymore. Shut it off and it goes back to running okay Could this be a stuck lifter, seeing how it comes and goes? Thanks
