I think you might have low oil pressure in the morning if you hear yours to come up with that possible theory. Oil pressure would be one of the noticeable things you find when you look at the main bearings and mine are clean and normal wear.
Snrusnak: the head seem to have normal wear nothing i see that may cause the rocker arm to fly out. i going to rebuild the motor completely and take measurements and see what has warp or what spike while driving. I rather be sure nothing is warp or crack then just replace and reinstall the "ROCKER". Things are better done right then having to go back and be to late.
I didnt say that now did I?
