Spring/Keeper interference with Rocker

GUYS!!!!!!!!!! I think I found it!!!!

Appears to be a bad rocker; She's blown out. Motor stopped perfectly for me to finally see it. Cyl4, Int rocker is gone.

It's got a weird notch to it.

Going to re-prime the lifter and see if it still does it.

Next order of business... Budget rockers, or OE replacements? This is not a big HP machine, nor will it ever be. It is a family cruiser. Suggestions?
