I wish I knew exactly what the solution to the prob. is. But try some belt dressing. Its like belt "grease". Just go to autozone or advance auto and ask/ look for belt dressing.

Good luck

do a little more investigation, man. where's the sound coming from? Front of engine? Rear of it? in the drivetrain?

Most likely it's an a/c pulley, either tensioner and/or idler pulley. Just take the a/c belt off, and start the car. If you're bird's still chirpin, look/listen to the main belt

tensioner is my guess, mine sounds like a freight train

I would check the belt tension. Does it do it when you first start the car? Only when the a/c is on? What did your neighbor do to fix it?

Normally, if it has something to do with the belts it will make a screeching sound, but I have never heard a grinding sound. At least out of my experience with car problems, which isn't much.

my neighbor said it doesnt do nething bad to the car nd that he learned to live wit it....its in the front nd it only happens after i drive for a while, stop the car nd turn back on...or excellerate fast nd then when i slow down it starts...im brining it to a fbody mechanic a few towns over from where i live on frieday....ill let ya'll know whats wrong...THANKS!

tensioner and guide pulley. i got 5$ on it.

[got-a-ls1]

yea a/c pully is my guess. You know those cost like 50 dollars and you can only get them from the dealer? atleast thats the only place i could find them... rediculous.

[third_shift|studios]

fuck that. look for some one parting out a wrecked ls1 and boom. you'll get it for shiping. thats what i did.

Air pump check valves are another possibility. Our 2000 SS does it and its embarassing as hell.
