Oil sump:
- Small screws are 1/4"-20x1/2". Use 7/16" wrench. Torque to 7 pound-feet
- Large screws are 5/16"-18x3/4". Use 1/2" wrench. Torque to 11 pound-feet
Valve Cover:
- Screws are 1/4"-20x1" or so. Use 7/16" wrench. Torque to ~7 pound-feet.
Do bear in mind that the AMC engines use all SAE fasteners, not ISO. You might get a metric socket that happens to fit some screws (common crossovers are 5/16"-8m/m, 7/16"-11m/m, and 3/4"-19m/m,) but they'll still be just far enough off that you don't want to make a habit out of doing it.
When you put things back together, either use LocTite #242 (or equivalent) or RTV on the screw threads to retain.

Yes your torque wrench will work. Also I reccomend the rubber gasket, I tried RTV twice in a row. No matter what I did the RTV leaked. Rubber gasket solved the prob.

I haven't looked at the black stuff before, but yes Permatex is fine and I wish I would have seen the black when I did mine. As for the oil pan gasket, make sure you specify that you want a one-piece rubber gasket.

RTV? I only use:
BLACK - General use.
COPPER - High tempeature applications, or self-grounding sensors.
I've had consistently rotten luck with the blue, and the high-temp red gets beaten by the copper anyhow. Using only two types keeps my logistical train short and simple anyhow.
I've never put RTV on the ends of the rear main when I've done it, either. Haven't had any leaks. Can't be doing something too wrong...
Oh - and a 150 pound-foot torque wrench is stupid large for something like this - you'll want to use a 1/4" drive or a 3/8" drive, which will make it easier to set to the necessary 7 or 11 pound-feet of torque.

Good to know! We have 3 XJs and 2 WJs between our family/close friends, all with the 4.0. I recently did my rear main but I'm sure I'll be digging in another one at some point.
