So hose #2 appears to assist in evacuating crankcase gasses. Though it should only help when there is no boost. Upon boost, there should be a check-valve to prevent a positive pressure in the crankcase system.

Could this hose be plugged so it's eliminated from the crankcase system? Thus vacuum will only be done through the hose connecting to the intake pre-charged pipe.
