<VV> Bent Push rods

[Michael Kovacs]

Lets see if analysis is right:
  The lifter is pushed by the cam.
  The lifter moves the push rod.
  The push rod interfaces with the rocker arm.
  The rocker overcomes the valve spring pressure.
  The valve stem moves inside the valve guide.
  The valve opens in time to miss the piston.

Things that can go wrong??

 The valve hits the piston.
 The valve stem binds in the valve guide.
 The rocker arm doesn't move.
 The valve spring is broken.

I has a similar incident with a 460 Lincoln. The rocker arm cocked (nut came loose) and the push rod did not like it. Replaced the rocker arm and stuff. Ran fine after that.

Any body else have a clue. I'd like to know too.

We have a 110 motor and the pushrods on #2 cylinder get bent. We have replaced the lifters to try and cure, but the problem still exists. Has anyone had this happen?
