Hydraulic lifters should never need a hot or running adjustment. If they come out of adjustment, then either the rocker nut need fixed or replaced, or you have a bad lifter that needs replaced, or a bent pushrod that needs replaced, or the cam lobes are wearing out. Once the surface is worn more than a few mils, your cam lobes will wear VERY quickly because the surface hardening is gone. My vote: Replace the cam, lifters, pushrods, and rockers before it kills the crank with the bits from the ground off lobes. Learned that one the hard way.
