The 2 previous answers are the general rule, the other is owners who
continue to insist on adding a lead additive to their gasoline. Short answer
is DON'T.

Can only assume valve got stuck in valve guide. Happens when clearance is
not
right after rebuild or bronze guides are used.

Listers....Saw this recently in my area ...
Does anyone have experience with this problem and what happened and what was
your conclusion???
PROBLEM:
Motor with under 5K miles since full rebuild - never over rev'd.
One pushrod jumped out from rocker ball - expected nasty noises...
Tappet adjustment nut was tight after jump.
Pushrod slightly bent - as expected, but not enough to permit jump.
No follower damage.
No valve or piston damage.
Compression maintained.
SOLUTION:
Replaced pushrod and tappet screw.
Motor runs just fine.
What happened and why?????????
Opinions please ..............
