I've noticed, that while under load mostly, i hear what seems to be something rubbing on the passenger side of the motor. I can also faintly hear it while at idle with the hood open. I really don't know how to describe it, but it sounds like metal rubbing against each other. I guess you can compare it to a rotor and caliper rubbing? Performance does not seem to be harmed with this either. It's quite annoying as I am passing people during regular DDing. It just sounds like two pieced or metal that are spinning and rubbing against each other lol.....I don't know how else to describe it. Is this normal? Any ideas?
