The first couple seconds is me showing where the noise is generally coming from, but you can hear it as well. It's a popping noise. Then I put the mic closer to hear it louder. What could that be?

Anybody have an idea?

sounds like your timing belt cover is loose. Apply pressure to the cover and see if the sound goes away.

I have the same sound when my ac is on. I think we have an airpump hidden down somewgere for additional vacume.

did you replace your waterpump?

Posted by: HectortheRican Mar 19, 2011 - 3:48 PM

Yeah. I did timing belt and water pump about 3k miles ago.

Another thing, this noise only comes out when I'm at nominal temperature.

Its the trans coupler inverter shaft bearings behind the oil pump, for sure.

All I thought when I read that was "so it's the flux capacitor..." lol

What exactly are those?

Belt dont have no knicks does it?

and only a Normal operating temp? It's for sure comming outta the belt area? could be some of the componet bearings.

Seems likely... Previous owners sound like they didn't know what "maintenance" meant. I'm just fixing things as they break. The belts are good. And yeah, it's definitely coming from that area and only at nominal temp, which means about 750-900rpm

just for giggles...get it warmed up, take the accessory belts off (I know, a pain) and then run the engine. If it still makes the noise it could be a timing belt idler or tensioner pulley bearing making noise. Sometimes they only make noise at a specific RPM or at high speeds the belt has enough force to make them spin.

^^^ got a point- but STOOOOPIDLY unlikely. not to be confused with impossible. We've all seen stranger.... lol

Try to zero in to a certin part. if you can find it down to be the alt/PS pump/ect. then you got a sold ground to stand on. ANY Click nose comes with a Vibration. Just a first though. (it's how i do it)

worse case- Gimmie call. You got my new number still, yeah? I'll help you out man.

Posted by: HectortheRican Mar 20, 2011 - 2:36 AM

Nah, I don't have your number. Facebooks! But yeah, I'll warm her up soon and give it another listen.

Posted by: Bitter Mar 20, 2011 - 9:43 AM

not that unlikely, but somewhat unlikely for that kind of knocky noise. Not impossible though....
