What tells you that a lifter is bad? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Alo, pulled one of my lifters tonight to see if I can find that knock from my engine on the driver's side, that thing must have been changed out with the engine rebuild... I can still see machining marks on the sides of it... If one of these things is collapsed, or bad, what am I looking for? I'm just gonna assume on of the springs is bad...

Also, how tight is tight enough for the engine to run off those tappets? I know the way to tighten them, start the engine, slowly back off the bolts on them until you hear a ticking, then tighten it slowly till it stops, then give it 3/4 of another turn, but how tight is tight enough to start the engine without damaging it?
