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.

the pump is not primed and won't be
so without spinning it fast enough?

you obviously don't have a clew how oil pumps have been engineered on ic
engines for the last 110 years.

the pump is not 100% positive
displacement

oh, it is negative displacement what % of the time?

Not bragging Jax.

yeah you are, and about a license a savy 18 year old kid could get.

How about sour grapes because you didn't get the same certification
that your 18 year old friend got?

I was studying physics when I was 18.

No training, no age requirement, no skill level, no standard of
competence.........

At age 12, I was being paid to repair engines that men my father's and
grandfather's ages were unable or willing repair.

Fixing engines is easy. Knowing what to fix is the hard part. For most
people.
