Venting the crankcase to the airbox is probably a great idea, in terms of reducing pollution. At the same time there is the question of what all that blowby is doing to the engine internals. I just disconnected the blowby hose at the airbox and fed that hose to a catch can. The airbox hole is now plugged.

You can see that the OCS is still in place. I'm thinking that water vapor will most likely collect in the drain tube. After a 50 mile ride I revved the engine up and could not feel any blowby even at 5-6K rpm.

I am running a 90C thermostat. The engine maintains 4 bars almost all the time. My last oil analysis showed almost no fuel in the oil.
