whining from engine compartment

i have a 93z28 rebuilt motor built up tranny cold air intake and custom chip and my car whines louder than my old supercharged t bird first off its not the power steering i just wanna know whats causeing it

This is pretty vague, LOTS of things could be causing this. Can you give us a general area where it might be coming from?

The first thing I would do is check to see if the whining increases with engine RPM. Then, take off the serp belt and run your car for a minute to see if the issue is pulley related. Break it down from there.

How can you be so sure its not the power steering?

It could be number of things, I would check all the accessories, the drive belt, and look for any vacuum leaks.

Mine was a whiner,turned out to be the A/C compressor.Funny how it sounded just like a power steering pump though.

looks like you've got a serious case of forced induction ;)


check all your accesories, you should be able to pinpoint where the sound is coming from
