Whining noise?

[IceMole19]

I'm new to the Mx-3 scene learned a bit from reading on here. I got one today a 93 GS, anyway everything on it runs perfect works perfect, decided to drive it as a daily driver instead of the Rx-7 which got works gas milage, the Mx-3 gets over 30mpg. Anway, there is a whine that comes from the engine when the rpm rises, doesn't matter if the car is moving or just reving it in the garage it is always there. I read and I thought maybe that friction gear but it doesn't sound like a tapping. Any idea on what it could be? If so can I fix it? How much do parts cost vs. a dealer or such? Thanks a lot.

Heck man, without being there it's hard to say. It could be your alternator, then again it could also be something else!<P>Check oil level, tranny fluid level, ps fluid level.

This may sound silly... but does it come from your stereo speakers.... I had that problem with my MX-3 when I got it... turns out the head deck had dropped its ground .... just a thought

Nope definatly sounds from the engine, I heard the friction gear is more like a knocking sound? I will try to locate the source tomorrow, he said it's been doing it for awhile.

Try looking for faulty bearings. I had a pulley that was making noise(the one for the steering pump if I remember correctly. I changed it and bam!, problem solved. And it was sort of a high pitched noise just like yours. :p

It's definatly comming from the side with all the belts, how the heck do you get down there though?

Took it to my uncles shop and they traced the whining noise to the PVC valve. The owner before me said he just put a new one on, maybe it's defective? Or do they all whine? Guess I'll go get one of those.

[IceMole19]

Well that fixed some of it, but it's still there when I drive

[IceMole19]

Where do you get these bearings?

i have some kind of whining noise too but i only hear it when i revv the engine AND i turn (i.e. to reverse out) i guessed the power steering or something like that but maybe i should inspect the pvc also..
