Squeak sound when I let off the gas?

[DevilSperm]

its sounds like brakes squeaking but it does it when i let off the gas...and heres the kicker...it does it sitting in the driveway. at first i thought brakes but when i revved it in the driveway and let off, it did it...i cant tell where its coming from..anybody else have a similar problem?

mine squeaked before...it ended up being the alternator bearing.

could it be the waste gate? do you have an intake? it could be the intake too, if you are getting any boost revving it

Its most likely your BOV. Most 1g valves make a high pitched squeak right when you let off the gas. You can even make them whistle a tune with careful throttle manipulation. :laugh:

did you install somthing they may be rubbing on the underside of your hood ? ( mytial bov does this.. its a tad to tall )

well i didnt really notice it until i installed my gm setup..but i can still hear the bov on top of the squeak....ill check it out today some more

I know I shouldn't have to say this, but you are using 2 people, one to rev your car while your underhood listening for the source of the sound.

P.S. From one long hair to another...watch the hair with engine running
