Whining sound coming from engine...

[BlackIce]

it almost sounds like a turbo!!! lol no but seriously wat is that sound? is it normal? i only hear it for a few minutes after i start the car and drive it. once its fully heated up the sound is gone. its not a loud at all btw.

I sometimes hear whining from the passenger seat area. It's weird, my last car had the same problem.

ya I think it's normal. I get it too.

Unless its due to weather (winter cold), its definitely not normal. I had a similar issue too and its been discussed a lot before as well.
