My car makes the same exact noise all of the time hot/cold it doesnt matter. i took it to the dealer when i still had my warenty and they opend the heads and they found nothing. Then they called one of the main chevy engeneers and he explaind to me that the sound im hearing is normal, he told me that some camaros/silverados have that noise and that its nothing to worry about and till this day i havent had any problems.

My car has a very similar noise. I've had the noise for about 2.5 months and it hasn't gone away. I haven't had time to pull the valve covers to investigate further, but I hope it's nothing serious.

This is identical to mine. It's present at all times, car can be hot from a 2 hour drive, it doesn't matter. Mine is also definitely not audible 2200+ or so. It's most noticeable around idle or 1-1100rpm.

check out the below posts. The first one is my car. It sounds about the same just not as loud. I have went to two different dealers and they both said it was a normal noise for the LS1. I have also listened to 1 Camaro and 2 Trans ams and all three made this same sound. The only difference between them is how loud it was. (by they way both trans ams were 2002's and less then 12,000 miles and were louder than the Camaro with something like 75,000). It seems to be normal or common and I'm not seeing any loss in performance so I'm not going to worry about mine.

my car is the fist link in post #16, there is a video of it.
Anyway I'm thinking about selling the car(thinking about buying a Vette) but how in the hell do I explain to a potential buy what the noise is. I could give them what 2 different dealers have told me " normal but we can't explain what it is". Like in my previous post I have heard a couple of other LS1's with the same noise just a lot quieter than mine. Thanks

mine does it too ... I'm pulling the air system and doing plugs/wires though in the next few weeks...
I've read and been told that it could be anything from injectors or coil packs to exhaust leaks, on up to sparkplugs loose, and beyond into valvetrain problems...
its just ******* annoying, and I know whatever mine is, its causing a loss of power so I'm assuming spark, and my mileage is ******* terrible right now as well.

Sounds like piston slap, mine has it too, mine reaches operating temp and it goes away. And the lucas oil additive causes the oil to foam thus getting air mixed with it. I wouldn't add that in if I were you on your next oil change.
