Yes, one chain from crank to hpfp. Another chain From hpfp to cam.
Without any belts on, is it noisy? I'm still confused ... If it was quiet without the pulley/no belts, it means that the noise is from something in the belt loops... Ac perhaps, or idler or alt or water pump ... Why didn't they check those instead of focus on the main bearing? Dumb dealer
