things that can go wrong with it are some wear on top where it contacts the camshaft. also, it's a Hydraulic lifter, so basically its too parts. the oil goes into the hole and spreads the two parts so it makes a better contact with the camshaft. the thing is, the spreading is very minamal and if that stopped it wouldn't be a huge deal. like i said...some ticking...

From what you said it's that "Hydraulic" in the name means just the lifter is made of two parts, having oil between them? How's that making a lifter to have better contact with the camshaft?
Please, shed some light about Hydro lifters, that's the one of few things I still don't understand well.

As lifters wear out, they fail to pump up fully and allow excess clearance between the parts.

Just to test my understanding: There has to be some kind of sealing (similar to piston and rings relation) between the metal button at the bottom side, and the rest of lifter's body, in order to make oil pressure push out the button; and that sealing is what wears out?
Do I sound correctly?
