FWIW the PCV fitting as described is definitely a truly closed system.
The vacuum can definitely be felt when you open the oil filler cap or
lift the dipstick off the sealing washer. Also when air is admitted in
that way, engine revs increase slightly as the air gets drawn into the
crankcase or rocker box and then imto the inlet manifold.
I am surprised that this mod hasn't been adopted more widely. It is a
major contribution to solving oil incontinence in our 'mature'
engines.
