It seemed to have less blowby and the leak wasn't as bad. Gene, the guy who makes the valve, suggested I run the valve at full flow to give me the most ventilation possible due to the size of the engine. I have considered a vacuum pump, but I viewed it as a band aid to the problem. It shouldn't be leaking at all.
