Reducing harmful hydrocarbons and noxious gases that come from your car or truck depends on the quality and performance of the parts you use. No engine is 100% efficient, and each one (even the one on your Chevrolet Trailblazer EXT) uses a PCV valve to control its positive crankcase ventilation. Almost always mounted above your cylinder head in the valve cover, your Chevrolet Trailblazer EXT PCV valve is a one-way valve that receives the escaping exhaust blow-by from the crankcase and routes it into the intake. This is much better than simply venting it into the atmosphere, which is what all engines did before they were equipped with a positive crankcase ventilation valve.
Trust in the value of the parts you get from carpartsdiscount.com and realize incredible savings on all your upcoming repairs. Don't let a broken PCV Valve bring about the demise of your car, truck, or SUV, and don't gamble with its condition by installing anything but the best repair parts.
