bad lifter?

Alright so I just picked up this ZJ, and it wasn't firing on a cylinder. Valve cover off told me that a pushrod got stuck in the rocker. All new pushrods and rockers, and when I go to put the problem cylinder on, the pushrod comes up short. I'm guessing the lifter is collapsed, but I figured I'd put it out there and see if anyone else has something to say. So, bad lifter?

What kind of noise did you have? Knocking or ticking around in the motor?

Either the push rod shrunk or the lifter did!

Even if the lifter collapsed it would be less than 3/16 of an inch. What is your valve spring height? Does the lash get less when you turn the engine over? Is rocker fulcrum nut tight? If all that checks out your looking at a worn cam lobe or severely worn lifter.
What cylinder? Do you lose coolant?
