High Pitched Engine Noise? So I was driving home from work yesterday, pulled up to a stop light, and started to hear a high pitched noise coming from the engine bay.
Pulled over to check the noise, and it sounds like it is coming from one of the pulleys. I noticed that the crank pulley does not rotate evenly, but has a slight wobble to it (other posts say this is normal).
Noise is slow but consistent at idle, but increase as the rpm's go up. Past 2500 I can't hear it anymore, but probably because my exhaust is drowning it out.
Thoughts? The car is under warranty for another 70k miles. Is it worth getting it replaced with OEM, or should I go aftermarket?

Something may have bounced off road and hit the pulley, when I went with a BBK 25% reduced pulley, pulled the old one off and the flange was all busted up with parts broken off. If you have a M6 it will be easier than replacing the A4, I have the A4 and paid my mechanic $100 to put it on, I could not have done it by myself with ramps.

If under warranty just setup her off and let them worry about it....
All first gen CTS-V's come with a M6...
