The flywheel/clutch cover is referred to as the bellhousing. If you look at it rom underneath it has the shape of a bell.

The hole may well be bigger..I'm under a lot of military vehicles and the memory is starting to fade.

The plug should only be in there when you are driving in water that is deeper than the bottom of the engine. If it is in there full time, and the proper gaskets are in place between the engine, the bellhousing, and the transmission, then it will collect any leaking oil. Then, when you depress the clutch, you will oil soak the disc facings and cause the disc to be oil soaked. This will cause the clutch to slip.

If you pull the plug, you will see if it is containing the leaking oil. Remove the plug and leave it in the glovebox like the decal on the dash says.

You can remove the PCV valve by taking off the steel lines on the other side of the fording valve, and then turning the pcv valve off while holding the fitting on the far end, towards the side valve cover. If you don't, then you could cause damage to the little cup like cover.

There are two fording vlalves: one at the PCV and one up top at the oil tube. They were commonly disconnected and then wired in the open position. The lever is normally in line with the tube in order to be open, hewever as I mentioned before it is possible they are assembled wrong and will then be wired closed, so you will want to make sure they are proper. I found that very problem about 30 years back on 67-08304 (a jinxed Jeep if there ever was one) which did not do the engine any fovours.

Funny I can remember that CFR after all these years, but can't remember my wife's birthday.

Your memory is good Rob (except wife's birthday), the bell housing takes a 1/8" pipe plug.

I think I see where the confusion comes from with Les.

When talking about a pipe plug being 1/8, the actual thread diameter starts at .405 of an inch (3/8 is .375). The size "1/8" refers to the theoretical diameter of the inside of the pipe. 1/8 = 0.125 by the way.
