main or rod bearing rap.

Raps light when idleing and goes away when rpm goes up.tore motor apart and have gouges in main bearings and some are chrome looking and others look like bronze or had a bronze coat that looks to be wearing off.also had no oil pressure after motor was warm.motor is a 72 400 bored 406 that had new pistons and bearings when i got ut.
