I am having trouble priming my oil system. I used the oil cooler line method instead of packing the pump gears with vaseline. I was able to get about a half quart of oil in the top cooler line and the rest went in the crank case. I am using a cordless drill on low speed, and have spun the pump for about 10 minutes before I run out of battery. I have an unheated garage so the oil temp is about 40 degrees, which I know is not helping me. Should I used a corded drill on high to get the pressure up? I know I am buildig some pressure as I can feel the torque in the drill, and also had a small leak at the oil cooler line fitting to the radiator. But I'm not getting any oil up on the rockers. Thoughts?
