The oiling system underwent a major redesign for this engine. I would describe it as a hybrid dry/wet sump system. The crankshaft cavity is well sealed similar to a two stroke crank area. It is so well sealed that it is difficult to turn the crank by hand, even with both cylinder heads off! You can hear the blowby similar to a compression stroke on a fully assembled engine. This is not a problem during actual operation because you can see the new crankshaft scavenge stage is much larger than the pressure stage so during operation there would be a low vacuum in the crank mains area.
The oil pump works as shown in the attached image, the output of the scavenge serving to oil the trans before draining to the sump. It is a clever design that makes the most of the pumping action of the scavenge stage and gives the return oil plenty of time to deaerate.
One feature I am unsure of is on one end of the transmission output shaft. It is a small roller bearing and there is a 6mm hole drilled in the crankcases that nothing goes into and is obscured by the clutch primary drive gear.
