I need to resurrect (get running) a 1976 ford 300ci 6cyl and was wondering what might be the best way to go about priming the oil system. The last time I fired it off after a while sitting, I didn't like listening to the rods knock. And thinking that if the rods were knockin the oil pump was runing dry along with everything else I was wondeing what my best option might be.

I understand I could probably pull the dist. and run the pump, but if it's dry too and by the sounds last time it will spin dry for a while, I was wondering if I access the oil sender, and that galley, or somehow access the center of, or the outer ring area of a modified PH8A oil filter with an oil line from an adapted pump up sprayer I may be able to wet down the pump internals along with the other important areas?
 
once the oil pump has oil in it the oil should stay in the pump assembly as there is no drain hole.after removing many oil pumps I had to be careful not to turn the top down and pour the trapped oil on my feet,floor,or anywhere not intended. That being said you should be fine just running it with a drill to prime up all moving components.
 
Take the coil wire off and crank it over with the starter for 10-15 seconds..If it's any good at all in the bottom end , it should be primed at this time... Many of those noises are piston slap or wrist pin noises in the Ford 6 cylinder engines..Any amount of priming shouldn't make any difference if it's the above noises.. If it's a rod noise , pull the pan and check the bearing clearances with plastigage to see how large the oil clearances are..
 
Do you have an O'Reilly Auto Parts store near you? They and probably others have a pressure tank that you fill with oil, connect a hose to the oil sender hole in the engine, then pressurize with air. That completely fills the engine galleries, oil pump, lifters filter, etc. With their loan a tool program, you buy the tool, use it, bring it back un broken and get your money back.
 
Sure makes a lot more sense than listening to it ruin itself, or pulling the pan, plastiguaging, re assembling then listening to it ruin itself anyway.
 
I agree with Roy. Remove the coil wire and crank it over a few times.It will allow the pump to refill the oil system without damage to the engine. I have done this many times on standby gensets. Both gas and diesel.
