sorry for posting all my problems to you guys, I hate to be a bother, but Im trynig to get my car to the point where it can be modified 
when Im on throttle I hear no noise, but when I let off the throttle (i.e. engine braking) I hear a clunking/crunching/grinding type noise. If I press in the clutch it imediately stops, if I let the clutch go it starts again. It happens less at high rpms, and when it gets around the 2000 rpms range it sounds really loud. I dont know if youll be able to tell by this description but just lemme know. If you have any questions, just ask.
Thanks again.
