do not soak lifter...lifter that are full of oil or pumped up will not let valve close during start up...and if the valve is hung open..it will meet mr. piston.
Wait a minute here. Lets say I pull in the driveway and shut off my engine.
My lifters are now fully pumped up. So I decide to re-start the engine...with the lifters fully pumped up, valves ain't gonna hang open.
I'm new Mopar and a hundred years Chev, so things may be different, but we ALWAYS pumped up new lifters before installing. I ain't talkin' soaking, I'm talking pumping oil thru the passage to be sure they were pumped up fully.
I have been so wrong on many things since I went Mopar, but a hydraulic lifter is a hydraulic lifter. Period.
