Would oil pump make a supercharger whine sound?
#5
Just finished chasing whining noise that ended up being Melling Oil Pump. We thought it was a throw out bearing or pilot shaft bearing, so we pulled the transmission and clutch. (LQ4 and T56) Found no problems. Put it all back together and still had noise. The pump is supposed to be centered, but this one was rubbing on the crank. As the motor warmed up, the parts would expand and it would get slightly louder. We centered the pump with a feeler gauge and the noise was gone. Nothing mechanicaly wrong with the pump, just not installed correctly. 14 labor hours chasing it though.
