Exhaust gases are replumbed into the combustion cycle to clean the air in automobiles all the time, not to far from what is being done to the newer four cycle model engines. You can bet the manufacturers would not do it unless there is some benifit (since it must add cost for the parts and machining). Crankcase vents have been plumbed back into the intake maifold of cars for years.

Get real guys, I would not do it unless there was some technical information. But all the new four cycle engines are being plumbed that way. If done correctly will ensure positive lubrication to the bearings, especially the cam bearings. It would seem improved negative crankcase pressure would enhance lubrication of the low end of the engine, especially the bearings. By scavaging the crankcase back to the intake provides that improvement.

Might as well get use to it since all the new engines are so configured.
