That is above my pay grade as some would say. On this topic I have a book or two, and at my level all I can do is use my common sense and decide the merits. Might be wrong might be.... heck how about Teflon coating as mentioned earlier, but on everything? Including the crank throws, the rods....just crazy thinking I know!

Coating or micro polishing a crank probably has some merit. The crank surface feet per minute has to be astronomical so anything that keeps oil from sticking to it would be beneficial.

The oil drain back theory through the valley make less sense. Getting the oil past the crank and rod and to the pan is much more difficult than getting it down the valley walls.
