It's not all the time that you find yourself in need of a replacement PCV Valve to fix your automobile. While it may not be difficult to buy replacement parts for Mercury vehicles, these days only the absolute best are required to repair your car or truck. Car aficionados know that a variety of special features is built into each Mercury, and know that only top quality replacement Grand Marquis parts will suffice when repairs are needed. The vehicle in your driveway is head and shoulders above the rest when it comes to all the vehicles these days.
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 Mercury Grand Marquis) uses a PCV valve to control its positive crankcase ventilation. Almost always mounted above your cylinder head in the valve cover, your Mercury Grand Marquis PCV valve is a one-way valve that receives the escaping exhaust blow-by from the crankcase and routes it into 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.
Bring your Grand Marquis back to life with the highest quality new or rebuilt parts from the experts at Car Parts Discount. Don't let a PCV Valve repair spell the end of your car, truck, or SUV, and don't risk lowering its resale value by installing anything but the highest quality replacement parts.
