Dennis,
I have been worried that you would give up on this. I'm glad you didn't.

Started it up again yesterday and there is still oil pressure, so yay! My carburetor is needing a rebuild, a lot of out of round holes need sleeved, so before I go further with tuning it will wait until I can replace.  Just happy it built oil pressure and nothing else ( Knocking on wood) is wrong.

  Remainder of the day was spent removing the transfer case and reseal where leaks developed. Will fill with gear lube later today after work.

At this point I figured it couldn't hurt trying another spring. This has been very frustrating.

Repacked the pump with Vaseline and also added some to the port on the input side of the block, Topped off the oil filter housing, poured some fuel down the carburetor and fired it up. Almost instant oil pressure and paranoid by every sound the engine was making.

Bought myself a new oil pressure gauge this morning. I only installed the nylon tube to the block leaving the gauge disconnected. I removed the oil line feed to the filter housing and using a syringe, squeezed oil in the line until it was being pushed out the new nylon tube. Installed new gauge, reconnected oil line, added oil to housing and put the cap back on. Cranked over motor, still no pressure registering.
Found TDC on motor and removed oil pump. Removed relief valve retainer and the plunger did not freely fall out. Had to lightly tap it on the work bench. 🤔  When I put it together the plunger was moving freely. I also cannot recreate the plunger getting stuck. Going to try a different spring and clean the valve again. 

Using a zip tie I can stick in the oil pump feed port and get to clean oil, so 99% sure there is no blockage in the port.

   I use an old oil pump that I removed the gear from and use a drill with a rod flattened on one end to turn it to test all my rebuilds. This way I make sure there are no leaks or problems before start up. You have to remember to prime the pump and turn it counter clockwise with the drill. Probably not necessary but I also turn the motor over by hand while the drill is pumping oil through the system.

  If everything is put together correctly with pre-lube, start the engine. If oil pressure is going to be 10 psi at idle, you may not see any at cranking speed. If nothing shows after 10-15 seconds, shut it down and look for a problem. If al is right (of course it is, right?), it will show up. Running for a few seconds with no oil pressure, if lubed properly at assembly, is not going to hurt anything.

Filled pump before bolting to the block. Filled oil filer housing. Used a syringe to fill gauge port. Still no pressure.

I just filled my pump with oil & bolted it on, then once the engine was in place and in ready to go I removed one of the oil galley plugs & used a large syringe (available at farm stores) and injected oil until the galley was full. Put the plug back in, disconnected the coil wire & cranked it over until I saw pressure register on the gauge.  Assuming that you have prelube on the bearings it won't hurt anything, as there is no load on the engine to speak of.

  While the block was down-side upwards and before i bolted the screen on, I poured some oil down the pump inlet into the pump. Once the engine was in the jeep, I started it. Almost instant oil pressure.

Ordered gaskets and wheel cylinders last Monday hoping to get it by Friday with them being shipped 2 day air.  Should be here tomorrow Confused  Sun is out so I removed the car cover from my chassis to evict spiders and anything else that may have moved in.  LOL

  Real question for those whom choose to read this thread, I know what I did ( more then once)   How did you prime your oiling system?

Disassembled the oil pump and thoroughly cleaned out. There was some debris where the oil relief plunger sits. Maybe enough to keep it from opening? Guess I'll find out.
 Clearance between the lobe of the rotors is .010" ( .010" or less allowed ) Although on the high end,  I'm within specifications and that should have netted me some oil pressure.
 Outer rotor to pump body is .008" and not to exceed .012". Good there. Rotor cover is flat, I did this when I assembled the pump the first time. I double checked anyway.  With no gasket and the cover plate attached I cannot spin the rotor. Good there.
  I need to order all new gaskets as I've gone through all my spares so this will wait until those arrive.

 To me it looks like the grooved area is just left of where the cotter pin drops in.  Some one on another social media network sent me a link to Haines Garage's site where he shows a O-ring but he placed that one to the right of the cotter pin. ( Reference to my photo above)
