boost leak? vac leak? Is the CEL on?

**downhillracer** · 01-02-2009 06:16 PM

is it rpm related?

could be a bad idler pulley bearing but I cant really hear the noise all that well.

**Turbo1A4** · 01-02-2009 06:26 PM

either a boost or a vaccume leak is my guess

A fellow AZiner buddy had a similar noise comming from his air box area. We found the ''bleeder valve'' to be the culprit, they get clogged up pretty bad.

sounds like wind....blowing past a camera.......
thats all i could hear.

wow didn't realize there was so much wind noise..i think youtube enhanced it

It is a bit rpm related, if I put it in first and slowly move, the noise is sped up slightly

There is No CEL. There is no boost/vac leaks, recently checked for leaks

FourRings, he said he was hearing a whining noise which is nothing like what mine sounds like..I guess I'll have to get a better video without the wind ruining everything. Ill take it to a parking lot and try making a new video

Idler pulley bearing seems to be a good start though...is there any way I can confirm / check?
