That is usually a sign that the valves on those lifters were stuck. Enough hydraulic pressure developed inside the lifter when the engine was turned over that the barrels have have expanded and are now stuck inside the tappet. Grab the barrel of the lifter violently with a pair of vice grips so as to crush it inward, yank it out of the tappet and discard. It was not any more good anyway. Lo siento mucho.

If you can rotate the engine by bumping the starter, that may help.


I can just rotate the engine at this point by hand with a 1" socket on the crankshaft since there is no compression.

Hahaha! Here is a man I can relate to. It would make sense since the tapping noise was coming from the front and middle of the engine when I did my long screwdriver stethoscope trick. Each of those locations have a frozen lifter cylinder inside of the tappet. I'll be sure to give that a try. I was going to get a little beat of heat into the tappet as well to see if it helps loosen it up.

If you had stuck valves, you will at a minimum probably want to ream the valve guides for clearance and/or install new valve guides (which are available). My experience, including the tool I purchased to ream my valve guides and the tool I made to remove/install them is here:

Well I was able to get one of the stuck lifters out without much of a fight. It froze with about 1/4” exposed and I was able to get it out with some vice grips and some light hammer taps.

The second one is determined to stay in the motor. There’s maybe a 1/16” exposed and I’ve been messing with it for a couple hours now. Any thoughts?

Take a small freshly sharpened pin punch and collapse it inward. Turn-repeat.

I ended up welding a washer around the top and was able to hammer it up and out. My god that was a pain.
