I recently changed the rear main seal in my ranger during a full engine re-build and to my dismay, it leaked. At first the leak was so bad that it actually puddled in my bell housing because I was tuning my carb for a while while parked facing up on a small incline. Once I faced down when I drove away I left a decent oil streak on the road.

I've since put a few miles on the truck, and I no longer see a drip at the bottom of the bell housing; the area seems to be drying up some. I'm not complaining, but what gives? :dunno:
 
Or is it actually from the corners of the oil pan that need a gob of silicone to seal up? Maybe the rear main seal rolled on installation and leaked, then by some miracle it straightened out and sealed. If that's the case go buy a lottery ticket.
 
Yeah, I dunno. I made sure to use rtv on the pan seams and it's dry as a bone. It's a weird situation but I'll take it haha.
 
It's no longer leaking as all of the oil leaked out?

Probably not but I bet it's happened to someone.

Haha, nope. I've been checking the oil level and the bell housing every time I park. As a matter of a fact, every seal I replaced does not leak. Weird.
