Default Re: Positive ventilation crankcase issue

all engines are an "air pump" meaning the push air up and down the cyl.
plus if your engine is still new, the rings have not seated, and you will have more blow by, than when they are seated.
no rings available to the common guy seal 100%,
so you will have blow by, and with out the PCV hooked up, it will go everywhere,

you DO want the PCV connected , and functioning. it relieves pressure inside the crankcase, when there is pressure,inside the crankcase, it has to go somewhere, (oil leaks)

besides the PCV only works at high vacuum ( light throttle).
soo when you mash the pedal, the PCV closes, and does nothing.
and when you let off, HIGH vacuum, and crankcase pressure relieved!
