When the engine reahes 2000rpm it starts to make the sound of pieces of metal rubbing on each other and then it stops once it reaches 2250rpm. This is a new engine that was recently swaped and it had 40k miles on it and it looked brand new. Also when idling, it sounds like a diesel engine. Any idea what causes this?
