Sure does when you miss a shift...valves float. Pulled the heads and cam towers last night on a 2.4 and knew before starting the teardown that the compression numbers on 123 and 4 were 90-95% but 5 was dead and 6 was 60%. I figured bent valves. Now with the heads off and pistons exposed, it's plain to see....littlle divots in the pistons from both intake and exhaust valves, and the 5 and 6 exhaust valves are indeed bent. I'm going to presume that as long as the pistons aren't broken, that my best bet is to leave them alone and focus on the top side. I figured that trying to polish out the divots might create an imbalance between the pistons and that the volume in the cylinders hasn't been affected. My machine shop will disassemle the tower and heads and check all the valves and guides and machine and replace where necessary. This is only a 2.4 and my interest is not in owning a $6k rebuild. Anything else I need to watch for here?...I'm psyched to clean up the outside of the motor as it goes back together...maybe detail a few things. ..using the suggestions from Waynes book.
