Thank you, Used Red MN. I did not significantly clean it up, although I did take off the bell housing plate that is mounted between the flywheel and the engine block to get a better look at the seal, and I removed some trash and hay that had somehow accumulated in there.
My thought was the same as yours: it does not look like the rear main seal is actually leaking that bad, if at all. I did an in-frame overhaul on this engine in 2022 (my first one), and the engine starts and runs great, and it has a lot of power. It does not smoke. I know it is leaking bad, though, because it accumulates a huge puddle under it. I definitely believe that it will leak 1-2 quarts per day.
When I bought it in the spring of 2022, it only had compression on two cylinders. I replaced the valves (two were completely rusted out and the remnants of the valves had destroyed two pistons), had the head milled, and replaced the pistons and crankshaft bearings. I had a friend who is a mechanic help me roll the rear main bearing in place, and I am worried that we might have messed something up in terms of sealing when we were messing with the main bearing. We never replaced the rear main seal because I never split the tractor. I do not recall installing any sealing packing on top of the rear main bearing cap, and if so, I guess that would be the problem. It is also possible that my friend installed something there and I do not remember it.
Should I fix that by dropping the oil pan once I get the tractor back together, removing the rear main bearing cap, and resealing it? What packing should I use there?

Today's Featured Article - Upgrading an Oliver Super 55 Electrical System - by Dennis Hawkins. My old Oliver Super 55 has been just sitting and rusting for several years now. I really hate to see a good tractor being treated that way, but not being able to start it without a 30 minute point filing ritual every time contributed to its demise. If it would just start when I turn the key, then I would use it more often. In addition to a bad case of old age, most of the tractor's original electrical system was simply too unreliable to keep. The main focus of this page is to show how I upgr
