Sound
DEFINITLY top end of the motor. Thought it was a rocker for sure, took driver side apart, nothing, everything looked perfect. Still have to do passenger side but I wanted to ask if anyone has any ideas? It still drives great and seems to have not lost any power, if anything less gas mileage ( Lifter sticking open?) maybe bent a rod? Sounds more of top end passenger side...very very slight stumble when free revving in park only at around 1300RPMS.
Any ideas before I tear it apart so I know any extras to look for just incase?

sounds like a bent pushrod.
