I'm pretty sure I have a leak at the dist. too, I've noticed that from the start since I bought it last April. I thought at first that my clutch was saturated with oil because of all the oil dripping from the dizzy on the bellhousing, and when I would drive it to the mountains it would slip at first (from not being driven much/city driving) but by the time I got it "warmed up" from an hour at freeway speeds it wouldn't slip at all.
That theory proved wrong yesterday when I finally got the trans. out; the clutch area was DRY and had NO oil residue on it. It was just burned up pretty bad lol my mistake.
Good call on having the flywheel resurfaced. I always do that anytime I put a new clutch in.
I did a quick search yesterday and found you stating that a few times to other people. Figured it was a good idea, and after removing the trans/t-case as a whole unit yesterday, I DON'T want to have to do it again because I overlooked something. So yes, rear main will be replaced too since it's accessible.
I figure, replace rear main, dist. o-ring, and check tightness in general (esp. oil pan since it looks leaky) and then drop in a quart of that oil stabilizer/stop leak and see if it's enough to get rid of my mess. I don't have a "trickle" or "drip" of oil ever, just a lot of residual in general...so whatever is leaking isn't leaking very bad, just a small leak *IMO
