Well, that is discouraging.  You mentioned the oil pick-up.  Are you sure it's clean?  Many of us have horror stories about the crap we find in the screen.

when i hold it up to the light i can see thru it, so i'd say yes.

scene my last post i was able to make pressure. i had the gear off the pump, and turned it with a drill took 30 seconds or longer to make pressure, out the pump back in, and no psi. the pump was dry.

 i made a  tool a 5/8th fine thread bolt to go in place on the over pressure cap, with a 1/8" hole to use a hand pump oil can to put oil in to the pump, and still notta.

the oil pan is down, and i heated up the oil pick up, as per a tip i got the other day. oil sticks to the screen, and cloggs it. so the pump can't suck up any oil. and why when using the drill it had the delay before i had pressure..... so i had 2 table spoons of a tar like substance drain out, and a lot of smoke ! once the pan is up, and i hit the key i'll let ya know how it went.


fyi i started this in jan ,  might sell or trade it soon ? if i can't get  pressure

Glad you got it figured out!

long story be short, i put in another pump with out a gear, and used a drill to turn it. it was all  ok . the gauge i had got at auto zone wasn't working. so i spent 30-40 days dealing  with a bad gauge. hope to make fire today. thanks to every one who helped.

If I remember correctly, he said it was the one that is a bit harder to see.  Hope this makes sense.

The "no oil pressure" mystery has been solved.  The engine builder did, in fact, leave out one galley plug.  Fortunately no dire consequences apparent, as she is purring like a kitten.  Supposed to warm up in a day or two so I can get it out on the road for the maiden voyage.  Thanks to everybody who helped with this.

congrats :)    which one did he leave out ? if you know by chance ?

Wow! Two different threads running with similar issues!  Not a good week for oil pressure!

There is some good info on the 3B Page in the Engine Rebuild article. There is an image showing where to look for the nozzle (it should be in the same spot on the L-head since it needs to squirt directly at where  the gears mesh):

https://cj3b.info/Engine/Rebuild7.html

And also, check the oil float (that round flat pickup hanging down into the oil pan. It should have a gasket so it can pull the oil up and into the gallery to the pump.

The plugs, IIRC, look the same inside and out (location of some of those holes inside):
https://cj3b.info/Engine/Rebuild2.html

Location of two external plugs on driver's side:

Also some good images here:

Not sure if this will help but a close look to verify some things will help a lot to eliminate a few things.

were to start.. :o

 i swapped pumps ( i have a spare engine on a stand to steal parts from ) the spare pump has no drive gear ( broke the org gear , so i stole for the org pump :'( ) with the spare pump in and no gear i drive it with a drill. ( rev is the direction i want to go  ? )  i used a hand oil pump and put oil in the rear galley were the oil psi gauge plugs in, poured oil in to the filter. ran the drill for 30 seconds natta.  i dropped the pan and checked for oil plugs, both are there in the bottom near the pick up. pull the fuel pump, and oil line that hides behind the fuel pump. oil is coming out the hose from the filter. pulled the brass 90 and verified the plug in the front of the block.

so on a crazy note, i put shop air 40 psi in the rear galley, air went down threw the pump an saw the pump turn,( have the side cover off ) then herd the air gurgle in to the oil pan  :( so then i put oil in the rear galley and put 30 psi of shop air in the galley ( had the drill in the pump so it didn't turn, air still went down to the oil pan and gurgled again.

so in the need for knowledge of how this works ! i put air the spare block, same hole 40psi. ( had the oil pump spot covered with tape ) pushed the air in, air did not go to the pump !  :o   it was in side the block some were, got brake cleaner, put it in the oil galley, and added air. it came out the rear crank main.

now what ? pull the bottom end ? :'(

BW, I spoke to my engine builder today and he said that, although it's a long shot, there would be a remote possibility that the oil galley plug(s) could have been left out.  Can you tell me what this means and why would they have been removed in the first place?  I mean, the engine worked great when I took it to him.  Why would he have removed said plugs?

Now then, I have never heard of a timing gear spray nozzle.  I had my timing gear cover off once and never saw anything that remotely looked like a nozzle.  Just the hole in the cover where the oil hose attaches.  There is supposed to be some kind of a nozzle there?  How would that affect oil pressure?

yes, i have pulled the oil pan, and other parts to verify the oil plugs are in, even the front one behind the motor mount plate. they reduced the spray nozzle for the timing gears to help build oil psi

Thanks, BW.  Good explanation, helps a lot!  I guess I did know about that timing gear oil jet - the word "nozzle" threw me off a bit.  As for the galley plugs, I learned something new today!

  The oil galley plugs are always removed from a block in the re-build (another example of the difference between a rebuild and an overhaul) process so that the galley passages can be cleaned out.
  Installation of the timing gear oil jet (nozzle) is covered on page 49, paragraph D-84, in the Service Manual for Universal Jeep Vehicles. The oil jet can be seen in the picture of the timing gears on page 48, although if you didn't know it was there, you wouldn't recognize it.  You do have a service manual, don't you? :)
  The nozzle, or jet, is installed in the front end of the main oil galley, and if left out, will dump all the oil from the pump into the front cover and back into the oil pan. Oil returned from the oil filter is surely a source of lube for the timing gears, but it is a supplemental source, not the primary one. The timing gears can live without it, as the old practice of blocking or removing the oil filter shows. The oil jet is the primary source of oil to the timing gears.

Good stuff, Rus.  Thank you.  I was hoping to avoid pulling the pan, but it is looking like I may have to do that next.
