Yes, the KV's are heavy-duty glorified PCV valves, I know this. They create vacuum in the fact they let air/gasses out, but not in. The difference between a KV and a regular PCV valve is the fact the KV will not leak air into the valve cover no matter how much boost you throw at it unlike a stock PCV valve. If you don't want to believe they work that is fine, but I can promise you that they do as I have personally used them as have MANY other people on both N/A and boosted applications with very positive feedback. I also think that you have it in your head that I am bashing on your venturi design which I am not and have in no way implied in this thread.

Similarities in the two products being discussed:
-less crankcase pressure
-no more dipstick pop-out
-fewer/smaller oil leaks
-smoother running engine
