I know specs weren't the same on these old vehicles

But should I just get used to the small oil leaks? The overdrive, transmission, and transfer case were rebuilt to be more or less like new a year ago. But they leak a small amount of gear oil all the time. Not enough to pool on the garage floor. but enough to form slow drips around the seals. The rebuilt engine was leaking a bit more out of the rear main seal. I stopped back by the rebuilder, and the fording values were stuck closed. He said the engine needs regular air pressure most of the time to maintain the right oil pressure inside. We opened the values, and it's dripping way less. What is in there might even be the residual buildup from before.

jeeps don't leak, they mark their territory

Most rebuilds on 50 to 70 year old mechanical units are done to no more than overhaul / service limits today. Not to new limits. Expect a wee bit of seapage and play.
The new guys to the M series jeeps almost always get initiated the hard way to what happens if you leave the fording valves closed. Most are lucky and notice the poor performance and ask around and usually an old timer who learned the same way will say, "Before you start burning the clock and money make sure the fording valves are open!".

There are two fording valves on a M38. The one in the pic at the link above and one on the left side of the engine between the intake manifold through the PCV valve to the valve cover. See the details in the "Downloads" section:

Jeeps don't leak - just like dogs, they just mark their spot...AND...If the jeep isn't leaking, its out of oil.
