So theortically if i run up to 5000rpm , and do Not use the extra 1/4 turn. My lifter will bleed down and loose lift? Cause i dont see it happening at idle or cruise.

They want that 1/4 turn or full turn in case it bleeds down, creating lash/space between. Then lifter plunger/internalspring takes up the space from collapsing lifter. Or something. On a light spring rate valvetrain and mild cam is this even a reality?

When the lifter stops ticking while i set it running, the plunger should already be slightly depressed. Maybe that IS the perfect amount of preload.
