I too would like to know. I can't tell what noise I have, be it lifters or piston slap but my 2001 Camaro has always been noisey in the same RPM range. Mine however doesn't seem to go away and it's annoying as hell. Chevy replaced my lifters, etc one time but it still did it. Anyone have a solution to this annoying problem. I know it's somewhat common cause of 5 friends that have Camaro's, 3 of us have the problem. Thanks for any insight or suggestions. Even something aftermarket would satisfy my desires. I just want the sound gone cause it annoys me to here the rattling / tapping sound as I drive between buildings and whatnot as it echo's back at me.

Yeah, I get it too, it lasts a while, and I can always hear it to some extent at idle. When its cold it does it 1000-1500, then again at around 2500. It goes away after about 10 minutes of driving, but like I said, always does it a tiny bit at idle. I don't have a warrantee anymore, so I'll just deal.
well at least im not alone.hopefully there is something to quiet it down some.............maybe someone has tried something that might??????i have extended warranty but id rather not have someone tear mine apart to hand it back to me not fixxed. anyone tried anything with success????

The piston slap is caused from the rings being gaped to small from what I have heard. As the engine heats up the rings expand a little and lessens the noise. You could have the rings replaced( I dout GM would do it under warranty) but its not really that hard on the engine.

Turn up the stereo! LOL! Seriously I have had it for about two years. It goes away as soon as it is warmed up. I just live with it cause I know its common with other LS1s. I race it weekly! Insane Clown Posse at 3/4 volume works!
