<VV> found cause of damaged piston, and is there a dipstick tube o-ring?

[Ray Rodriguez]

     Our theory is that at some point there was excess lash on this valve 
allowing the pushrod to dance around, at some point the block end of the 
pushrod came down on the retainer clip instead of in the dimple.. causing 
the valve to hit the piston and breaking or knocking loose the retainer clip 
in the lifter.
