When you resealed your oil pump, did you check and tighten the 5 screws on the back of the oil pump? These screws can back out over time and cause pressurized oil to leak from behind the pump and out through the crank seal. Other common leaks that I see regularly are valve cover gaskets, cam seals and the separator plate at the rear of the engine. If it hasn't been changed before, it's most likely a black plastic piece that has since been upgraded to a metal plate. Usually if there's oil at the rear, on the y-pipe, I'd lean towards a separator plate, but sometimes oil can leak up front and the road can blow it rearwards....hope this helps.
