Blasting is complete...now it's time to get to work. Not too bad of shape overall, thankfully. I don't like all the braze repairs as I'm going to have to grind them out and replace with welds if they are compromised. I included a picture of 2 x 3/8" holes that were not supposed to be there that I filled in last night, not too bad if I say so myself

Sadly the motor has developed a small oil leak at the rear after running it for an hour or so. I'd hate to have to take it out again if it's the rear main or welsh plug. It did seem to slow down once it got hot. I'll let it go through numerous hot and cold cycles and see where I am prior to putting the tub back on in a month or so.

There were warnings about military vs civilian rear main seals, but as I recall the civilian ones were too tight. So tight in fact, they were causing rear bearing problems and leakage because of the amount of heat. Since then, some dealers have had proper rear main seals made up.
That warning aside, I have had it where the rear main seals take a little bit of time to set in. And they can be replaced while on the vehicle. I used to do them in about an hour, although it almost takes me that long to get onto the floor and back up again these days.

That's good to know, Rob...I'm really hoping this thing just needs to "run in" to seal up. You cracked me up about taking an hour to get down and up again, lol.

Got the carb kit from Brian today so that's on the list to do soonest.

I have rebuilt 3 jeep engines recently and I will only use the BEST made rear main seals as I have not had a single leak from any of them. The one engine I had to replace a rear seal as it was burnt up and took out the rear main bearing from being too tight of fit on the crank.

Hi Dave, can you elaborate on where you sourced your seals in the past? I went with neoprene vs rope which If I remember correctly I got from Brian.

The last engine I did was about 5 years back. The lack of availability of the rear main seal swayed me to putting in the rope seal. It leaked for a very short time, then sealed up.

John Bizal sells what is reputed to be the Best brand rear seal. The old part number for the military is reported as National 5585, but no longer made. The civilian seals that were a problem are reported as part number 800093.

Just have an engine back from rebuild. My engine builder threw away the rear main as supplied with the kit (from a MV parts dealer) because it was way too tight.
He opted for the old school rope seal for my build.

OK sounds good, I guess time will tell what happens with this one. I'll definitely refrain from putting the tub on until I see what happens in case I need to pluck the motor out again.

I've started welding up holes, dealing with dents and applying color to some of the bigger pieces that were previously sand blasted. I'm fairly happy with the results although the hood kicked my butt a bit causing me to sand and paint 3 times. You can see in one picture I ended up with some dry spots which were unacceptable. I had to go to Cloverdale in Lloydminster (~2 hours away) to get a new gallon of paint and was shocked to find even though the codes are the same and the dot on top looks good, the paint obviously isn't correct even after drying. Guess I'm going back next weekend I also had a great conversation with John Bizal and now have two types (Best Seal & OEM) of rear main seals to try which he recommends to have on hand in case one is too tight. Once the fenders and tailgate are painted it's on to the tub which will take time.

The tailgate is definitely going to be a challenge with the amount of repairs needed. I cut off an unexplained extra tab that was welded on the tailgate which has a match on the tub also. I intend to weld up as much as I can with bondo used sparingly. I'm looking for suggestions on how to deal with the formerly brazed holes which will hamper welding where they need filling. Metal filler maybe?
