dose it go away when the car warms up, thats from clearence with the pistons. if it doesnt you could have a loose rocker, bad lifter, or streched timing chain, (last is unlikely if stock)

yea it knocks when at idle, just gets really bad when i accelerate. yea i took it to my friends dad is is a mechanic and said it was the back left valve that was causin the trouble he said. He wasnt sure but he said it was most likely the thing. How much would fixin that cost do you think if it was a bad rod lifter???
