Vanishing oil leak

So when I bought the truck a couple weeks ago it had a small oil leak that would drip for just a bit after driving it and it heated up. I kept trying to find where it was coming to but never could track it down. The previous owner had taken it through some serious mud because I washed probably 20 lbs of caked on mud and dirt from the undercarriage. I hosed it all down and sprayed the lower engine, tranny and surrounding lower areas with degreaser to try and pinpoint the leak. I checked the usual suspect but the valve covers were bone dry. I have never seen a difference in oil level either, I have been checking it constantly. Since it was dripping from around the bellhousing I just assumed I was in for a real main seal job, so bought the seal and have been waiting for the time to drop the tranny and do it. Well each time I would drive it since doing 2 degreaser jobs and hose downs, it seemed like less and less oil would drip to the point a few days ago where it just seemed to stop. Is it possible there was just a bunch of old oil built up somewhere that would heat up and drip down and now that I have cleaned it really well that's just it? Or is it leading me into false hope... I put almost half a bottle of seafoam in the crankcase the other day (after already noticing that the oil drip had stopped) and have driven it around a bit to clean everything out and still am seeing no drips. I really don't WANT to drop the tranny if I don't have to, but already have the main seal waiting for me. What would you guys do?

If it ain't broken, don't fix it.

Leaks can come and go. If it's not leaking anymore, no need to mess with it. Just keep an eye on it and if comes back, positively identify the source of the leak and address it.
