Oil Pump Blues
Is there any better solution than this worthless little blue oil pump O ring? I just rebuilt the motor with tighter main and rod bearing clearances for the third time this year. Started the motor, oil pressure is low, goes up to 40 then down to 10. Looks like another O ring issue and I have to pull the pan off in the car. This is the second time this year that the O ring has failed to seal. Is there any better part to use, better seal, square ring, different method, gasket, anything from GM? Anybody
