so i heard a tapping that sounded like valve knock and well thats what it was....anyway what happened was the #7 intake pushrod had mushroomedon the rocker side and im not exactly sure why it would have done that. i know it was loose but the only scarring i found was the concave part of the rocker where the pushrod sits. and it wanst bad at all. so cmon all you gurus....im stumped. is it just from it slappin up against the rocker? i thought that they were hardened steel? wouldnt the rocker give first? ohh there was also two little scars on the spring retainer.
