How about all the parts in the engine being motored over that run dry
until you are spinning the engine over fast enough to splash the oil ?

which parts is that? The pistons?

the cylinders have an oil film on them to begin with. the bearings requiring
pressure oil do not have pressure oil to them until they have pressure oil to
them, which they can't get until the galleys are first full of oil and then
pressurized.

you were supposed to have learned this well before you got that license you
brag about having.
