even if you disconnected them from your intake and whacked a small filter on the ends, you'd be creating another problem - unmetered (hotter) air entering the engine.
it's all part of a circuit where 1 and 13 are under vacuum and suck the ccv gases in to be burnt up. 6 and 14 are the fresh air supply lines, to replace the ccv gases, oil vapour etc sucked out via 1 and 13. ever wondered why you dont see oily gunk in your intake pipes? |
I forgot about this thread. After thinking about it a year later and reading your post I agree. 6 and 14 with the check valves are only able to "suck" air out of the crankcase. When running boosted under load the PCV valve closes and all is well in the world. So when you are idling you are sucking air in through lines 6 and 14 and into the intake manifold.
