We have a 03 Powerstroke that is leaking oil off the front of the Engine, through the valley, and off the back of the motor. We thought it was the o-rings on the high pressure oil pump, but none of them seem to be the prolem. It looks like the oil is coming from the bottom of the pump. Is there other o-rings under the pump? Or is the pump prone to other problems?

Never heard of that problem before, but there's always a first time. Try to safely spot clean the oil soaked area, in order to precisely locate its origin, and go from there.

My 2003 showed the same signs. My diesel mechanic indicated turbocharger seals were leaking.

I located the source by checking the drop spot. It turned out the drain valve from the fuel filter canister had failed and was leaking. The spot on the garage floor was diesle fuel, not oil.
$63 for a new valve.
While there, I replaced the fuel preheater for $163.

Your problem could be the same.
