Certainly not meaning any disrespect or trying to sound like a know it all.
IMHO, a properly installed PCV system will not cause blow by (crankcase positive pressures), as it is a vacuum based system. Not to say an improperly designed PCV system will not result in oil being introduced into the intake causing smoke. Simply, if you have the PCV removed and have excessive crankcase pressure causing extreme oil smoke to come out of the PCV port, you probably have additional conditions adding to the problem.
