Reused distributor. New Compcams cam.
I have been moving the intermediate shaft with my pre-oiling adapter.
I have tried having someone bump the motor over while I press down on the distributor.
I know how to get it pointed at the number one and all that, but I cannot get this thing to drop down.
My shaft looks fine, but could it be damaged?
The intermediate shaft seems a little loose in its hole, is that a problem?
Does the orientation of the vacuum advance matter?
Really struggling here and most of the post on the net are Chevy posts, and I was wondering if there was anything that was peculiar to Pontiacs.

They can be a bugger sometimes to drop in. It might take a complete revolution or two to get it to go.

The vacuum can should be position on the driver's side for the widest range of adjustment.

Is the distributor turning when you are bumping the engine?

I've done this trick many times and it can make you dizzy.

First off, you must have the #1 piston at TDC.

The vacuum canister should be on the same side as the routing line. My favorite side is
on the driver's side.

Stupid question, but I will ask, are you sure you have a Pontiac distributor in hand and not
the long shafted Chevy?

If you have the correct one locate where you will run the #1 spark plug terminal. Since these distributors move counter-clockwise, you must position the pump slot so it mates with the distributor end. When the gears mesh and the distributor begins to seat, is should drop right in. The housing rotor must precede the terminal, that is, it must start to mesh before the terminal, perhaps by a half inch or more. As it meshes with the gear it will rotate the rotor toward the #1 terminal you've selected.

BTW, the gear on the cam for a Pontiac meshes only with a gear from a counter-clockwise Pontiac gear.

Bitterman? Angry or Arthur's chauffeur?

I'm just a man who reads books, and that knowledge makes me bitter. I'm going to take a video of me trying to put this in tomorrow, and link it. I think my physical technique is bad, but can't see how myself.

So I have two pontiac distriibutors. I took the gear off my old one, so that there was only the shaft. Sucker went right on. Does this mean that the problem is with my cam gear and distributor gear? Could the cam be off? Should I get a new distributor gear? I spent hours turning the intermediate shaft and keying the motor over and turning it with a break bar to no avail. I'm running out of ideas.

So I I just confirmed that the gears aren't meshing by taking apart the old distributor and snapping off the dong on the distributor shaft to eliminate the possibility that it was hanging up on the intermediate oil shaft. So now I am trying to figure out why the cam gear is not meshing with the distributor gear, but it still is going in about 1/3 of the way. I am going to buy a comp cams ~451 distributor gear to make absolutely sure it's the cam before I pull the motor. Does anyone have any advice at this point?
I am thinking that there is a problem with the endplay perhaps? Perhaps I drove the rear main plug in too far. I don't know. I am struggling to figure this out.

This is definitely strange, neither distributor with their gears on would drop in?!

Just a shot in the dark,but is the distributor gear installed correctly?
I remember in highschool I put a new pick up in my Gran Prix dizzy,and I installed the gear upside down,then couldn't figure out why it wouldn't mesh with the cam gear correctly.

Sounds like the groove on the oil shaft is flared and not letting the distributor come down.
