I understand all of that....
But saying a Pcv makes your engine idle and run better means that some air is being introduced into the system to change the air flow ratio. The same thing could have been done with a bleed or jet change.
I agree that the amount of
oil you are getting is not excessive and prob can be reduced further by limiting the suckage at cruise rpm.
I have never really been a PCV valve fan simply because it's something else that's not really necessary (unless you're in an emissions testing state) and it's something else that can fail with bad consequence. A pair of valve cover breathers are sufficient for crankcase venting and *most* guys will drive long enough to get the
oil hot and boil any condensation out of the system.
With all that being said, the above setup is kinda cool from an engineering standpoint.
