Eliminating the PCV system from an engine is a bad idea. It is a myth that PCV's hurt performance. In fact, your engine's crankcase requires ventilation in order to remove toxic fumes that pollute your oil and cause undue pressure which forces oil out of any place that it can go. Generally speaking, the flow of air comes from the intake manifold through the breather on one side of the engine, down through the crankcase, up the other side, and out the PVC, back into the intake. I consider it very important to have the PCV on one side of the engine and the breather on the other. This helps ensure that the entire engine benefits from the air flow. Otherwise, you will create a mini flow on just one side that only involves the valve cover area. Oh, and it's a PCV (positive crankcase ventilation) not PVC (common plumbing pipe - polypropolene something or other)
