Nothing obvious while running, but oil pools at the front of the main cross-member. It doesn't seem to be leaking from the valve cover, fuel pump, distributor, front main seal, or rear main seal (not 100% about rear main). I suspect the oil pan itself has a rupture, but I can't see above the cross-member to inspect the bottom of the pan.
Sound like a pan leak? Can I remove the pan with the motor in place? Not much clearance between it and the cross-member?

I recomend using a shop crane to raise the engine. The book says to remove motor mount pass though bolts, loosen (not remove) the tranny crossmember bolts, then raise the engine. Now reinstall the pass thru bolts above the frame portion of the motor mount and set the engine down on it. It's still a tight squeeze, but doable.
BTW, I did it using a floor jack. Din't forget to put a block of wood under the oil pan if you use a floor jack. And it's a good time to paint that nasty ol' pan too......

BTW, if the rear main is the culprit, would you advise pulling the tranny or motor?

Places to jack from: My 250 has 2 bolts on the head (passenger side) where the battery ground attaches. Thats my front jack point, my rear is a bolt hole at the very back of the engine (rear center head). I have brackets for these two spots. It balances the engine nicely.
