Ok so there's a new noise in my car and I'm not exactly sure what it is or how to describe it but I'm gonna try. If I leave it in, say third gear and keep it at a steady 35mph, i'll hear this noise that sounds like a chain being dragged accross the ground kinda going "gring, grind, grind, grind, grind". It's not constant but it like pulses.

I popped the hood and tryed to find where it was coming from and the nearest I can come up with is it sounds like it's coming from around the cam gears. Like in that area somewhere. I'd like to get this problem resolved before she gets boosted this summer. Anyone? Ideas?
