I am rebuilding a Jeep 4.0.....How do you pump the oil thru the engine before you start it.......It appears that the oil pump is hooked up to the distributor and the cam.......So if you spin the distributor, you are turning the oil pump AND the cam which is turning the engine over.....Therefore, my conclusion is that the only way to do this is to pull the coil wire and turn it over with the starter.....Any thoughts?
