Hello everyone, new member here. Had a question about the ccv, blow-by topic. I did the search and read a bunch of posts. I have a question about "normal" vapors under the valve cover. Should I be able to see any of the vapors with the oil filler cap off? If I see any smoke do I have blow-by or should you "normally" see some smoke?
background: just replaced the valve cover gasket with a clean of the ccv system in the process. had oil soaked air filter but I think that was caused by the leaking valve cover gasket providing the highest pressure air source available. I see a bit of smoke when oil filter cap or rear intake vacum source line removed.
thanks for any help and/or ideas.
edit: also another question. what would normal pressure under the valve cover be? Does the metered hole in the rear of the valve cover and the fresh air from the air box keep the pressure more neutral? or is the air under that valve cover lower then outside air? thanks again
