On my B18B I have a non-vented oil cap, my air filters don't have any vents on them, the oil breather on the spark plug side of the block is being vented to air with a small K&N filter and the PVC plug hole in the manifold has been blocked off with a bolt threaded in. This is the setup it had when I purchased the car.
I understand that this could give me blowby/seal issues with pressure building up.
I found this page which is helpful:

Now what should I do for the PCV valve. The hole in the manifold is threaded and the PCV valves are not threaded. I assume there is something that threads into the manifold and has an attachment for a hose, to run to a PVC valve? Then I would run that hose to the oil breather and get rid of the little filter?
Thanks for you help!
