Okay i developed this issue back in the middle of the summer after i just just did a delete of my smog pump and put a short belt on the car

when i rev over a certain rpm about 2500ish the car will make a metal on metal grinding noise
like a whistle but it sounds like pure metal on metal

someone said check the belt but u can't hear it under the hood only when the hood is close or ur in the car revving... from 2500rpms its consistant

doesn't seem to hurt performance...

and i was thinking it and my cousin just suggested it, i could have spun a bearing but wouldn't that make the car pretty much undriveable??

any one have similiar issue? bearing a easy fix or does the engine need to be torn into for the fix?

!. if it was a main bearing or rod bearing, I would think you would be walking right about now.
2. If by chance it is either....I have not yet developed a way to replace a rod or main bearing without tearing the motor down.

If oyu have all your accessories, it coud be a bad alternator, a/c compressor, or a variety of rotating equipment issues.

still have the A/C, its coming off as soon as i can get somone to evacuate the system, hopefully thats the problem cuase i know that hte a/c clutch does no spin at all

MadMan@TheWheel

Voila...Hopefully that is the problem mang

belt slippage, or compressor bearing failure, also inspect the pulleys for wobble

did you plug the heads in back where the smog crossover tube goes?

Alero99

the smog pump was disconnected by the dude when he did my exhaust he welded that metal pipe thingy shut and disconnected everything fine... when i took the pump out i left the bolt that holds teh bracket in the block cause i didn't wanna leave it out... ill find out when i remove the a/c and put new pulleys on
