Fisch Posted September 26, 2012 Share Posted September 26, 2012 This noise started a couple of weeks ago, and it generally only occurs when the car is cold or warming up during idle. Once it's warmed up, no noise can be heard. When the car is cold though and making the noise, I can either push in the clutch or bump the gas pedal and it will go away. Any ideas, guys? Sorry for the link, the attachments aren't working correctly for me for some reason.

Nrw Posted September 26, 2012 Share Posted September 26, 2012 I'm going to go with throwout bearing Link to comment Share on other sites More sharing options...

TenzoGT Posted September 26, 2012 Share Posted September 26, 2012 Almost sound like a vacuum leak... What rpm does it stop? Link to comment Share on other sites More sharing options...
BigBad Posted September 27, 2012 Share Posted September 27, 2012 I am pretty sure it's your Idler pulley on the AC belt side. The bearings are gone. Mine made an even higher pitch whine at idle until I replaced it. Link to comment Share on other sites More sharing options...
Fisch Posted September 27, 2012 Author Share Posted September 27, 2012 I'm very meticulous about my oil changes, and I'm always sure to top it off. My engine has always sounded like that. The squealing noise is what the issue is. The noise will stop as soon as i raise the rpm's slightly, as well as engaging the clutch. I was thinking throwout bearing as well. That can't be replaced unless doing a new clutch correct? And how would I go about checking the idler belt pulley bearing? Link to comment Share on other sites More sharing options...
BigBad Posted September 27, 2012 Share Posted September 27, 2012 There is no easy way to test the idler pulley bearing but a new one isn't much money and is easy to replace as a first step vs the throwout bearing which requires a breakdown of the clutch to replace it.

Fisch Posted September 27, 2012 Author Share Posted September 27, 2012 Yeah I'm going to look for them tomorrow online, and I'll most likely order one. And if it does end up being the throwout bearing then I suppose I should just replace the clutch as well. Thanks all. Link to comment Share on other sites More sharing options...
