I don't know Jay, you pretty much have to pull the engine out. You need to get it high enough to clear the front of the oil pan so it can slide past the K member and don't forget the oil pickup which will find a way to snag the pan, it is definatly a PITA item.
What part is leaking, the sides, the back or the front. If is in the rear, it may be the rear main seal, in the front it is probally the timing cover, on the sides your f'd.
