hello guys,

let me try to be as descriptive as possible. 2002 w/ 30k miles. I noticed the sound a couple of days ago only because I was looking at the motor w/ the hood up at the time, if I didn't just happen to look, I probably wouldn't have noticed anything.

so when the car is warm (after driving for a while, probably around 30min +) if i stop the car and go outside, i can hear a faint ffft ffft ffft sound, kinda like tearing a piece of paper(ie tear pause tear pause tear pause...). its only present when the motor is on, and if i rev the engine, the motor sound overpowers the ffft noise, so i can't tell if it gets faster w/ the engine or not. i tried listening around, and it seems to be eminating from the front of the motor, around where the belts are. i can't pinpoint exactly where its coming from other than that.

on cold start, there is no noise. it only comes when the engine is nice and warm.

any ideas? anyone else w/ the same sound/noise/problem(?). normal? any help will be greatly appreciated! thanks guys.

pull the drain plug and inspect oil for metal.

 

Maybe it's the smog pump.

 

changed the oil. all is well. sound still persists.

smog pump?

 

Buy a mechanics stethoscope, and start listening around underhood to locate the noise. Trying to fix a noise online is next to impossible. We can't hear it, The only thing we can do is guess at it.
