Default pre-oilers

The "splash" does NOT come from the rod ends going through the oil in
the pan. If the oil level is that high the oil temperature is going
to be real high with the pressure too low due to the oil foaming.
The cam lobes are oiled from the oil that is THROWN from the rod
bearings and the crank bearings, Pre oiling just gets more oil there
sooner.

Why? The "splash" comes from the crank counterweights and rod ends going through
the oil in the sump. A pre-oiler pulls oil from the sump and moves it through
the passages to make sure the journals and bearings are lubricated at start.
Seems to me that the "splash" will happen just as fast either way.
