i have a breather on each valve cover and im using the stock pcv setup, when i changed the upper intake plenum gasket i noticed alot of oil was coated on the inside. so i capped the pcv temporarily and i guess the breathers were blowing the air out since it had no where else to go. at like half throttle there is slight blow by im not sure if its normal, i think it might just be a pcv issue, this engine has about 4-6k on it and nothing crazy has happened like detonation or error from me. is there a catch can setup or some other way to ventilate the fumes better?
