Thanks guys for checking your documentation and for the suggestions - - - all good ones. I'll be calling Chip this morning to check on a new assembly which is probably just as easy, albeit more expensive, than tinkering around with the adjustment to find the bad o-ring or seal. To be honest, I'm just a little nervous screwing around with the adjustment now that I know it controls the engine oil pressure (as opposed to what I suspected was the bypass pressure of the filter), even being careful with the turn count, aux oil pressure gauge, etc. Having said that, I'm sure I'd need to check the setting on a new assembly to make sure it wasn't just put together without adjustment.
I used the tractor over the weekend doing some BH work, checking the oil frequently. Didn't have to add any so the leak (drip) must look worse than it actually is. That however doesn't make me any less concerned with the leak or the mess it makes, or with the fact that the valve is exposed to all the dirt, dust, and moisture. Thanks RickO for the picture of the acorn nut. I didn't expect my missing part was an acorn nut, thinking it was more like a closed-end, threaded tube. I've printed the picture and will take it sometime this week down to a small, local business that deals in every conceivable nut, bolt, and fastener out there, aptly named York Bolt. Although it's a little hard to tell in the picture and by looking at the threaded tube it screws onto, I'm afraid a regular acorn nut might be a little shallow to accommodate the protruding length of tube. It looks like it might bottom out inside before the sholder makes contact with the nut. If they don't have something that looks like it'll work, I might just get a nut and have my cousin (a master with brazing and all sorts of welding) braze a small pipe nipple with an end cap to it. That way I would be able to install an o-ring or gasket washer to the threaded tube and snug down the make-shift cover for a tight seal.
When I finally get this thing taken care of, one way or the other, I'll post what I do, hopefully with a picture or two. Thanks again to all, for all the help and suggestions! No doubt I'll be back for more help in the future.
