I did a search and didn't find an answer. I am trying to get oil to the rockers on a 392. I have the pump priming rod installed in a 1/2" drill motor. I get instant oil pressue on the gauge. I have been spinning the drill for a few minuets, but no oil is comimg out of the rockers. How long should the drill motor have to turn the pump to get oil to the rockers? 2 mins..5 mins? Engine is a fresh rebuild that has been run before, but has sat for a few years. Thanks for any answers.
