I'm having the same problem with my 2001 Explorer Sport with a 4.0 V6 SOHC. I have over 242,000 miles on it. After review with 3 different RMS and a dozen mechanics, we've come to the conclusion that there is slack in the crankshaft that's causing oil to pass through the rear main. When I originally took it in, there was only a seep. Now, a small puddle build on the ground whether running or not. I also noticed while working closely with the last mechanic that I am beginning to hear a slight intermitten knock at the bottom of the block which seals the deal with the crank theory. I'll be getting my long block rebuilt soon.
My suggestion would be to start it up, watch the drips and keep an ear out for tapping/knocking loud or quiet at the bottom half of the engine. If you do hear something, take it in to get mic-ed by a mechanic. That will tell you what's going on and where. Good luck! Hopefully it's something else.
