When the RPM drops below about 1000 a nasty rattle comes out of the engine bay. I thought it was the waterpump at first so I replaced it and the rattle continues. If I take the supercharger belt off, the noise continues. When I take both belts off the noise goes away. I totally thought it was the water pump since stickin my face down in the engine bay thats where it sounds like its coming from. If its the crank pulley would it make any noise with both belts off? Im tempted to run it with just the S/C belt on it and see if the noise happens. Im pullin my hair out so any help would be appreciated lol
