While it may not be difficult to find replacement parts for GMC vehicles, these days only the absolute best are required to maintain your automobile. Anyone who operates a GMC knows that when it comes to maintaining their car, truck, or SUV only the most superior replacement parts will do. Your GMC dealership isn't the only place to buy genuine or original equipment quality parts to repair your Sierra 1500 HD. You purchased your Sierra 1500 HD because its dependability and trusted quality appealed to your senses; so why would you be okay with anything but the best when it comes to superior quality auto parts?
Achieving maximum fuel efficiency while reducing emissions on 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 GMC Sierra 1500 HD) 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 Sierra 1500 HD 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.
