Oil pressure 0

[Michael C Henry]

Check the actual pump. A small chunk of crap can lock the gear rotor. With the pickup tube removed does your pump turn freely in both directions. It is supposed to pump when rotating counter clockwise. If you connect the pickup tube to the pump and emerse the pickup in a can of oil to prime the pump , the pump should turn counter clockwise with a noticeable drag on a 1/2' or larger drill motor. It will be verry difficult to hold on to with your hands. Chuck the pump and pickup in a vise and have someone hold the can of oil to the pickup .You'll have your hands full with just the drill motor.
The distributor drives the oil pump not the other way around. The better oil pump drive shafts are available Summit and Jeggs. If for some reason there is a problem with your oil pump. Prescision Oil pumps have blue printed Melling High volum oil pumps. They convinced me to go with a truck pump with a larger drive input than the car pump and had a dandy shaft to go between it to the car disrtibutor. Then Milidon and others make a priming drive shaft for priming with an counter clockwise rortating electric drill motor before installing the distributor. watch the oil run and squirt . Then if there isin't oil you have other problems. You want the pump primed ,the filter full , the oil cooler and hoses full when you next try to restart your engine. make sure if you have a remote filter that the oil flows to the element from the side and out the middle. The other way the oil encounters a check valve and flow is stopped.
