Engine oil seal
Is the wear ring concrentic around the crank snout?
Are there no slingers or deflectors behind the snout to keep the oil off the belt?
I am sure my front seal from Cummins has the installer to set the depth, we know if the rear main seal is not set properly, it will leak like the Exxon Valdez.

After the second time I would probably drill and safety wire all the critical bolts on and under the timing cover.

The latest Cummins recommendation is LocTite 5699, which is why I bought a tube.
I think I'll do it with that, no paper gasket, and use locTite blue on the screws. I cleaned up and tapped the old seal just barely into the cover to use as an alignment tool. After the cover is set, I can pull it out and put in the new seal.
Last time I did it it looks like I did Permatex black on the cover side of the gasket. Held till a couple of screws loosened up.
I was planning to set the seal pretty deep to get the best part of the seal past the wear mark. I'll look closely, and if the front part of the sealing surface is usable, I'll set it flush instead. No sense in sacrificing good crank metal to rust.
I'm off to get a couple of 125 mm long bolts to make a seal installer out of a bearing nut socket. Pictures to follow if it works. Best part is it shouldn't hurt it's function as a socket.

thank you for that update! i'll change my recommendation from the red RTV to the 5699 from now on!
I think the main thing here is that they recommend some sort of silicone sealer over the gasket. for whatever reason it may be. I know it's easier to clean off than old gasket if you ever need to remove it!

Yes. Seems nice and smooth, just barely can feel it.
I got the cover on, aligned, and tightened down. Spent considerable time cleaning up the mess in the front of the engine compartment. Still have to take the radiator to the car wash and pressure wash it.
I couldn't find any 12 x 1.25 x 120 mm bolts in town. Going to plan B.
BTW, for future reference as I will have the tools by the time I'm done with this bruhaha to easily install a seal blindfolded and with little space. How does one get a seal removed without removing the cover?
So far today I've gotten totally frustrated trying to get the Dodge seal to go into the cover. Tapped for awhile. Made a home made driver and it wouldn't go straight. Seemed to at last and I put a little force on it and wrecked the seal.
Then I grabbed the repair sleeve out of the Cummins seal and drove it on with little effort. Just drove it on cold with a piece of plate, 3/4" center hole and two 1/2" holes to match the HB bolts. It drove right on alternating between the bolts turning one flat at a time.
Tried to start the Cummins seal and ran into the same problem. I wonder if I should freeze it before I try to tap it in. Once I get it started in the hole, I have a home made driver that will put it home with ease.
If I have to take the cover off again, the die grinder is coming out and there's going to be about a .015" starting taper when I get done. This is stupid. The hole has square edges.

freezing seal will shrink it a little, I did like you said, radiused the entry, and I use a thick steel plate backing to lay the cover on, using a seal driver, patient frame of mind, luck, pita is in.
