A fellow on another board mentioned an Uncle Tony video that described this same situation
That is exactly what at least that one lifter of mine is doing. Start the engine and it rattles until the pressure shoots up, pressurizing the lifters. Shut the engine off, and at least this one lifter will bleed down almost immediately. Start it again, it rattles again until it pumps up.
UT did not explain how to tell if there's a problem before installing them though and I don't have the rest of my life to watch all of those videos and find out he never mentions it again
One idea I have is to pump them up with the primer then come back tomorrow and any that have collapsed are suspect - replace those. Repeat until I've got 16 that don't leak off. Maybe start with a new set of 16 and go from there. I'm kinda not happy about having to break in new lifters on the cam but that shouldn't be a problem. Right?
The next question is, what brand do I buy to replace these (Howard's) with?
