I'm trying to prime the oil on my crate 383 before start-up. Bought correct priming tool from Summit, removed the distrib. and am using a 1/2 inch drill. So far no oil to the lifters or anywhere that I can see. What am I doing wrong? Any suggestions would be helpful. Thanks !
I always plumb a cheapy temporary mechanical oil pressure gauge by the distributor.
Next I make sure the drill is turning clockwise. Then I listen to the whirring of the drill.
It kinda bogs down when it primes the oil.
Keep drilling until you see the oil pressure come up.
Then stop, rotate the engine a 1/4 turn and then continue.
Repeat the process until you start seeing oil.
It'll take it a bit to fill the filter and all the oil system, then bring up any pressure. I've had a couple of drills leak smoke and smell funny in the past.
A 1/2 " drill is a little light to prime an engine. A variable speed 3/8" would do a better job and not heat the windings so much.

Didn't do well in math class I see. 3/8" is SMALLER than half inch.
While a heavy duty, low rpm half inch drill may not spin fast enough to prime the pump, you certainly won't hurt it. A good 1/2" drill will spin fast enough to do the job without injury to the drill. Like was stated, keep turning the engine over as you prime it. Certain oil passages will be blocked depending on the crank position.
Just a thought here, Have you taken the oil pan off? Maybe they forgot to put the oil pump on. Don't say it can't happen, I've seen it done. Take out your primer and shine a light down the distributor hole. Make sure there's an oil pump drive shaft in there.
Yea the 1/2 inch is needed for sure. A 3/8 usually will not have the power. It also takes some time to get it up to the rockers. Give it a few minutes and you should see it starting to trickle out of the rocker arms.

You said correct tool , can you post a link to the tool , it needs to look like a dist housing not just a shaft ?
Oil primer from Summit-part number 055523640. The 1/2 inch drill is only turning about 500 rpm. Too slow?
Hmmm that number doesn't come up so I'm not sure what primer you have.
If it doesnt have the sleeve to tie the 2 sides together you wont be able to get the pressure up.

Yes, you are correct. Your math is fine. Sorry, I had it in my head he was going to use a 1/4" drill because I was just talking to someone who was trying to use the smaller drill and I advised him to use at least 3/8".

Instead of trying to find the correct priming tool, if you have an old distributor laying around, just grind off the teeth on the drive gear, (you need something to hold the shaft down so it doesn't jump up and beat up your oil pump driveshaft) Then cut off the top of the shaft where the rotor goes so you can chuck it into a drill. Drop the distributor in and hook up your drill. Viole! A priming tool.

That's what I use and I've been through 3 of them,why 3 you ask ,because when I loan them out they won't bring them back.
