oil pump priming
All right, I have my entire engine back together and I forgot to prime my new oil pump. Should I remove the distributor and try to run it with a drill, or will it be allright to just fill the oil pan and run the engine??
I dont want to damage anything, and am wondering if there is an alternative?? Thanks

Yank the dizzy and prime it. Sure, it's a little bit of pain, but the fact is you, like everyone else that's ever built an engine, got a little ahead of yourself and made a mistake. Don't cut corners this late into the game. Finish the job right. My $0.02 anyway.

I agree, take the extra few minutes to ensure that you dont waste all that money you just spent on that motor.

I primed mine with a electric drill on low speed using a long screw driver to the oil pump.. Pumpe for a minute then turn the crank half a turn and pump for a minute. Make sure that oil is coming out of your push rods. This is your last chance to make sure everything is right.

I have a tool especially for priming Chevy oil pumps. Forgot where I bought it though, since that was, like, 12 years ago.

Definately prime it. You can buy the tool or make one out of an old dist shaft end. make sure you get oil coming out of every pushrod and by the way you may go through a few drills if you do not have a very good heavy duty one. Try to have the oil warm or a heated garage if possible.

(Primes much quicker if you fill the oil filter first)

Thanks for all the great advice!! I will prime it for sure. I dont have a drill with a chuck that will accomodate a distributor shaft, and will probably use a screwdriver??

Hey rage'nrat638, how did you go about making the tool out of the old dizzy? Did you just hacksaw it and use a drill with a real large chuck?
I cant remember what the size is of the distributor shaft. I am at work right now and will have to look tomorrow. Is it something I can build quickly? I have a friend coming over tomorrow to help me drop the motor in and would like to prime it before that? Thanks for the help!!

Here's mine I made years ago from an old points type distributor.
You need to make one, the screwdriver deal doesn't work that well. See the grooves around the distributor body? They are oil passages that transfer oil to the lifter galley on the other side of the engine. Without the distributor body itself in the hole, half of the lifters aren't getting oiled properly. The oil just spills into the pan. Just grind all the teeth off the distributor gear, so it can rotate freely without interfacing the cam gear.

Just grind it down on a bench grinder till your drill will fit it.

Tim just did this 2 weeks ago as well. Just ground the gears off a junkyard distributor he got for free and then ground the top into a square. Then he had some old sockets kickin around and he fit the socket extension into his drill and 3 minutes later it was primed

I have the priming tool from NAPA and it has the oil shuttle passage and a top bushing so it runs centered .

Priming it is best, but if you ever find yourself in a bind or are working on a motor that is not as easy to prime as a SBC, you can do the second best thing. Remove all the plugs and spin it with the starter till you have full oil pressure. While this is not as good as priming without turning the motor, it is much better than starting one dry. If the motor was assembled with plenty of lube it doesn't hurt anything and lets you know you will have oil pressure when it hits, so you can break in the cam.
