    Is it possible for rocker arms to beable to loosen up a little,that's what my car sounds like to me,it only does it at idle,then when I press the gas it stops,sounds like the coupling or whatever that is inside the supercharger but its not my supercharger I've took the belt off and ran it like that,even did the hand turn test and its not it mines at 00 gp gtp if anybody dosent know

    Yes but if they loosen up they will \ can bend push rods. Sure it's not your lifters or flex plate making a noise?
