So I ran the motor minus the belt, the gen and new water pumps weren’t in play. On higher RPMs the noise was there lasted for 10 seconds then went away. Gassed it again noise came back for seconds then gone. I seemed to have isolated to the bottom fan pulley. It’s not touching anything . The noise sounds like a low whooshing . I have no oil pressure issues no fuel issues no over heating issues . It doesn’t happen at idle only on higher RPMS and even then I won’t do it.. I got a new gen, new Napa belt and it’s still there . Any ideas? Bearing?
