Adjustable PCV and oil catch devices?
I have recently installed the Wagner dual flow adjustable, and used a air/oil separator from Home depot ( air compressor small size.) Only ran it a bit before the weather got too cold to drive.
Seperator is catching a small amount of oil/fluid, and I no longer smell the blow by gases I used to smell. Will see how it works when winter is over. I know it's expensive, but I think it will be worth it.
