Zoltan,
It is possible to get the pushrod hung up on the lip of the lifter.

Subject: [VANAGON] Why are the lifters so hard?

I must have done something when I was working on the engine, because the
lifters got pumped up so hard, I had to adjust the valves to zero turn.  If
I just put on even a quarter turn, the valve would leak, would not close.
Is there a pressure release valve that is not working now?
Anyone knows this?
Air cooled engine.
