Rebuilt engine. New everything. New oil pump also. Put 1 full quart in the motor and started it up to let it suck some oil into the motor. Let it run a min and shut it off and went to add another quart and the tank over flowed. That’s how I’ve alwAys done it and it’s been fine. Gears are also on correctly. Oil filter was full also. New oil pump bad or am I missing something.
