Leaking oil from bellhousing

I ask because I have a very steep driveway and leaks.

The oil will move to the rear of the pan while going up a steep ramp or hill. It can then reach a level high enough to leak past the rear bearing and through the drain tube, and since a slinger is used instead of a seal, the oil goes out the engine. This is why farm grain trucks have a ball check valve in the drain tube.
