Valvetrain Inspection?..
Ok my valvetrain seems to be getting more noisy...I am suppose to go to the track Sat. and I want to maybe take a peek under the covers and at least see if anything is out of whack up there. ( I cant get to the lifters obviously). What should I be looking for?...Should I expect ANY up down slack of the pushrods?...Side to side movement of the rockers?...Basically my car starts to tick a little...and go away.....come back....rattle rattle...if I barely blip the throttle open from under the hood...I mean barely just for a second...I can get a clatter as it settles back to idle. As I drive...as it sweeps up past 2100-2500 slowly you can hear a soft jackhammer effect..but its gone above 2500. It still sees 6,000 and doesnt spit parts out..YET. Any advice?...

Rocker arms appear in good condition. They have only the slightest side to side movement at the trunion. The pushrods do not appear to be bent. So what does this mean?...I NEED lifters?...Or maybe just that there is some slack in the pushrods? I am doing a cam swap soon, but man I was hoping to leave the heads on and lifters alone. What do you guys think I should do?
