I realize that if all is normal, but your engine isn't normal at this time, it also has a sheer pin in it.
Edit: this really doesn't make any sense, dist is fine, cam is fine and wont pump oil but runs fine, but will pump oil with a drill and prime tool, something is missing |

My plan is to borrow a distributor from another motor and fire it up and see if that changes anything. Thank you everybody for your responses. I’m determined to figure this out. |

If the engine runs/rotor spins the gear is fine.
If the priming tool builds pressure, the oil pump and it's drive rod is fine. Must be the male 'key' in the distributor gear that's gone. Never head of it breaking but every few months it seems I run into something that I'm working on that I've never seen either.......so.....pull the distributor and turn it upside down and look at it. https://cimg5.ibsrv.net/gimg/www.off...9e728c8bb6.jpg |
I had this happen on the dyno one time with a slip collar dist. The engine ran fine, but had no oil pressure. The cam gear was engaged, but the oil pump shaft was not. Dropped the distributor a little and all was good.

thanks for the info! |
Look at the bottom of the distributed tang you can normally see if it was not engaged and slipping will leave shiny marked on the outside of the tang not in the center. Can you show pictures of the ware marks on distributer gear from camshaft is it close to center? |

:party-smiley-004:You have lipstick and are willing to share that info with us means a lot to us. Thanks. :evilb: |
On top of what's been said about the seating depth of the dist drive into the pump...Does the engine maintain pressure when you run it on the priming tool or did you just run it up to Pressure - hit 50 and stop??IF it holds there...you know the distributor driving the pump is your issue
I know of 3 circumstances where the issue was in the pan - (1) had a cracked pickup tube, (2) not mounted to the block securely and (3) the other was wrong pan/dipstick combo... with the dipstick, the jobber/hack put his engine together knowing that the dipstick read deep (read full before safe) and never got around to changing. Sold the engine to new owner who did an oil change to the mark (backyard boater *not a mechanical person more than what you can see on youboob) and ran the engine ....I'm sure it primed up until it cavitated |
