Have to disagree here. Breather caps were all that was available until around 1970 or so (give or take a few years). PCV systems have not been on cars since day one. The statement of
substantially accelerated wear is not substantiated.
Letting the fumes go to atmosphere will not accelerate wear as opposed to leaving the PCV system in place. And as has been pointed out, not recycling those fumes into the intake has advantages.
The average car will not see a benefit between pulling a mild vacuum and venting to atmosphere.
Will disconnecting the PCV cause error codes? I do not know. This could be a complication.
