its been doing this for over a year now, just now getting aggrivating.

when the car is first turned on it makes all the normal noises, piston slap, etc ... but when it gets warmed up there is a metalic ringing noise from the front of the engine i think. when revved up beyond 800 - 900rpm the noise goes away, but at idle its so loud you can hear it on the other side of the house.

this is ONLY the case when its warm, until the engine warms up its silent.


anything i should be looking for? its starting to drive me nuts so i'm motivated to fix it.

 

Your description sounds like a problem that's very common with the LS1 fbodies. If it's what I'm thinking of, it's simply a wire that has a washer that jingles when the engine is running. Causes no harm, and unless you're having serious issues you can't possibly hear it on the other side of the house. No way to fix it either, I'm afraid unless you're fond of supergluing things.

 

just figured out that it seems to be the A/C tensioner pulley

where are these wires with washers? i might go ahead and superglue that as a precaution.

 

check the idler pulley - these things to make a hell of a lot of noise - only 15 bucks ro so if you want to replace it anyway

 

where can you purchase the idler pulley, my friends been searcing for one.
