Grinding/vibration noise at certain RPM.
IVe noticed that my 3vze will make a grinding/vibration.
Seems to be at the same RPM(between somewhere around just above idle to 2k, I don't have a tach), moving, stationary, upside down and right side up. Im thinking it may be something harmonic, like a loose bracket or bolt in the exhaust somewhere (my pipes are all full of holes, this is definitely not a stretch) but Im not ruling out a belt or a pulley bearing.
Any ideas what it could be?
