I have this noise coming from my engine bay, sounded like whoosh whoosh. It seems as though it is coming somewhere from the crankshaft pulley or drive belt auto tensioner. Can someone tell me how to fix this problem, or at least tell me what it is.
(Car is a 2002 civic si)

Thank you in advance

 

bent crankshaft pulley maybe? should I replace it? is it ok to drive it because i really need the car for at least 200miles

Watch it very carefully as it idles. You should be able to see it wobble if it's bent.

I don't know about the noise. Alternator bearings? Some pulley on something isn't perfectly parallel to the belt? These make a little different sound, but I can't hear it from here.

Maybe you could use a piece of hose as a stethoscope to pinpoint the location of the sound...

 

found the problem, defect band in the auto tensioner. Thank you for the reply.

 

i thought it was a hidden BOV
