i have a bearing type noise coming from the engine bay (even louder with hood closed) sounds like a slight metal rub noise there are no leaks no performance issues and no signs of anything wrong... its noticeable but not loud i was thinking tension or another pulley but it sounds like it is coming from the motor itself anyone have any ideas? or had this sound and what it was? - vehicle 00 trans am 5.7l 59k miles

 

yea mine does that too. i'm not sure what it could be. it may be a squeaky belt or rubbing pulley. beats me... i'm not worried tho because just like yours, mine also works fine with no performance issues.

 

It’s the freaking AC belt tensions; they are the lowest thing to the ground and get most exposure to everything on the road, including dirt and water. I bet that’s the problem my friend, they don’t sell them at Discount either, NAPA carries them I believe. Other wise you have to go to the dealer

Put your head under the front of the car while its running, then you’ll know for sure.
Its annoying as hell

 

lol you got that right... when you stand at the back of the car all you hear a a sweet 350 puuurrrrr then you step to the front and all i hear is an annoying yet not too loud metal rubbing noise :o\ and you dont if its bad or good to go

 

I've replaced everything but the water pump and A/C condensor and I still have the noise (gf's car)

Not always the tensioners

...if they made them last forever...

 

i took a closer look and then got on the floor and listened and it sure sounds like it is from the lower part of the motor so most likely it is the ac that is making the noise im gonna try to fix it this spring if its not to expensive or even just bypass the ac... anyone else done this?

 

when you ask "done this" you mean A/C bypass or fix the noise?

Be absolutely sure you know where the sound is coming from. Sometimes you think it's coming from some place when it's not.

 

what i mean is even if its not the av making the noise what use is the ac when i have ttops and an LS1 muhaha
