Racing guys use this principle of exhaust removing crank case gas and shoot it out the exhaust .
I need space in the engine so the only way I can get this space is to remove the current cone filter placed between the ABS break unit and firewall - place this directly onto throttle body .
The two pipes from either side of the boxer motor that go into the airbox-place these onto breather filters.
Not delete the pcv but rather take atmospheric air into pcv .
Whetehr the intake to the either side of the motor being a boxer motor is taken from airbox or via filter to atmosphere - I do not see any issue with this .
The pcv always sucks into towards the engine side and never the other way around- this is why it has a vacuum one direction valve.
Many delete the pcv due to the spent blow-by and parts of oil are recirculated into the engine for exhaust emissions.
If they designed engines to burn clean in the first place there would be no need to have a pcv except for venting crank pressure ,which in the old days was just vented to atmosphere and the road .
The only issue I have is the third connection to the airbox that from my study of the pcv circulation would be a failure backup in the event of the pcv valve failure .
To explain - this pipe has three connections- one from top of engine - one to pcv valve and the last has a smaller diameter to the air intake .
Seeing the reduced diameter and the skewed angle- my deduction is that under normal circumstances the vacuum from the manifold has a significantly higher vacuum than this path .
If anyone else has insight to this I would be interested in your interpretation .
