Even with the 2 valves, if you have a proper setup, you will always have a vacuum source to the valve cover evacuating any dirty air, blowby, or other gasses. Like anything else in the automotive community there will always be differing opinions (i.e. engine break-in procedures) and that is fine; these KV's are just the opinion and route that I have chosen for my cars. I like the idea of a vacuum in my crankcase to reduce resistance on my crank and pistons. Now another thing I have noticed, is that since I installed the KV's on my Evo my mileage has gone up about 2-3mpg. I noticed this exact same thing on my S2k. I have no way to prove with 100% certainty that it was caused by the KV's, but my driving style did not change and it was an immediate observation I made with both cars.
