I heard (probably from the same guy who told my to keep the RPM low and
load high to seat main bearings) that if you have a leaky hydraulic
lifter that you should buy a new one and replace the guts in the old
one with the guts from the new one and reinstall the old one. This way
the cam/lifter mating surface doesn't change. When I did my rebuild, I
found the worn valve train was the main reason the engine was so tired
and I replaced everything with new stuff.
That's what I have heard. YMMV
