Newbie here: Explain where the "lifters" are and how they work I am just now starting to learn about internal engine stuff. I have the basic understanding the the cam pushes the pushrods and then compresses the springs and opens the valves. Where do the lifters come into play on this? What do they actually do and where are they located at? Can anyone provide a picture and possibly explain why a lifter may "collapse"? Thanks

It was my automotive engines text book from my spring semester, it covers everything about engines.....

Lifter's are the basically the shock absorbers of the valve train. they sit inbetween the cam and pushrods. They help to absorb the shock and to prevent seperation of parts in the valvetrain. Here's a decent explanation at the valvetrain. Only problem is they forgot the lifters. Look at the Pushrod section.

Lifters follow the contour of the camshaft lobe, this changes the cams rotating motion into a reciprocating motion in the valvetrain, also hydraulic lifters take up the slack in the valve train or "lash"

if a lifter is collapsed that means that the lil plunger inside that pumps up with oil to take the lash out of the system is no longer pumping up meaning u have excess lash so u need to replace it.....
