The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles these days. You purchased your Envoy XL because its dependability and longevity struck a chord inside you; so why would you be okay with second best when it comes to superior quality auto parts? GMC automobile enthusiasts have come to expect a certain level of reliability when driving their Envoy XL around town. When your GMC Envoy XL rolled off the assembly line, it was destined for a driver who wants trusted quality in their automobile.
Achieving maximum fuel efficiency while reducing emissions on your car or truck depends on your use of properly functioning exhaust and emissions parts. No engine is 100% efficient, and each one (even the one on your GMC Envoy XL) needs a system to control positive crankcase ventilation with a working PCV valve. Almost always mounted above your cylinder head in the valve cover, your GMC Envoy XL PCV valve captures and re-routes exhaust blow-by from the combustion process and sends it back through the intake. Before the positive crankcase ventilation valve, all blow-by was simply vented through a small filter element in the valve cover. This is a much cleaner method.
