Re: pulling oil pan
On my truck I used a bungee cord around the dipstick tube over to the frame so it would pull the dipstick tube directly away from the engine, holding the pan fitting tightly up against the inner wall of the oilpan.
Then with that secured, I gingerly spun the nut all the way off (although it would obviously still be captured by the dipstick tube) cleaned everything thoroughly with brake clean, and then applied a "caulk joint" of international gray around the fitting where it met the pan and then threaded the nut back down forcing the silicone into the threads, up through the center of the nut and squeezing it out from around the bottom of the nut. I then tightened it up accordingly and cleaned the extra off from around it and removed the bungee cord.
Otherwise..... nut up, pull the engine and fix the damn thing.
