Mercury Mariner PCV Valve

Keeping your Mariner in top shape is your top priority.

Obviously, you didn't buy your Mariner unless you knew that you wanted strength and a dash of luxury both impeccably combined into one car, truck, or SUV. It's not every day that you discover you need a replacement PCV Valve to repair your vehicle. Mercury car, truck, or SUV enthusiasts have come to expect a certain level of high-value when driving their Mariner around town. Anyone who operates a Mercury knows that when it comes to fixing their automobile only the most superior replacement parts will do.

Why PCV Valve replacement is so important.

Getting the most out of your car or truck depends on how well you maintain your engine and exhaust parts. No engine is 100% efficient, and each one (even the one on your Mercury Mariner) 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 Mercury Mariner 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.

You've tried the rest, now try the best.
