i've been hunting down a tick and finally pulled the intake and lifters. on the # 6 exhaust, the bottom of the lifter is scrathced and the edge is all chipped up. thatmean the lope is wiped. i tried to take a picture but cant get a good one of the damage. the intake was slightly scratched but no chipping. what next? all other lifters look good and clean.is there a way i can tell if the lobe is wiped by looking at it?
