Bad, bad, bad for the environment.
It is all part of your closed crankcase ventilation system.
Many years ago, it was determined bad practise, to dump oil fumes into the atmosphere.
The difference, if you were to re-engineer this to an open system, would be very minimal, as far as power output or fuel consumption goes.
If you really want to play, fabricate a cold air or " ram air " intake system.
Your engine & the environment will thank you.
