The Water4Gas PCV Enhancer is used to:
1. It filters OUT the sludge. It keeps your oil, engine and spark plugs cleaner, thus allowing your engine to have a much longer life.
2. It condenses the water out of the crankcase where we do NOT want it. If there are burnable gases flowing through, the PCV Enhancer is designed not to stop them but to allow them through, thus enabling a better and cleaner recycling of gases. Only oils, sludge and water will be stopped.
