The PCV system is an important part of you car's emissions controls. Please don't vent to atmosphere - you'll be spewing pollution.

Venting straight to atmosphere is not a good idea. The crankcase needs to be kept under a vacuum to prevent ring float. Ring float will increase blow by and you will lose HP.
