Mercury Marquis Valve Stem Seal provides excellent sealing against engine oil that lets the valve operate easily and does not let oil go into the combustion chamber. Thus, it will keep the combustion chamber clean and deliver a snappier driving experience with lower emissions. Each Valve Stem Seal is built with heat resistant elastomers that resist hardening during highway cruises and stop and go traffic. Thus, every Mercury of the Marquis line uses minimal oil after years of service. The precise lip of the Valve Stem Seal that works with the cam-driven valvetrain also protects the spark plugs from oil deposits that can cause misfires and safety issues. This Valve Stem Seal will power anything from a seventies sedan to a late nineties cruiser. In fact, it fits the Marquis of every generation without fuss because the factory specifications stayed constant throughout the production run. This compatibility makes things easier for Mercury owners and reduces storage space in roadside kits. A brand new Valve Stem Seal also provides some cushioning of the valve stem, damping vibration which reduces valvetrain noise and improves cabin comfort. As the miles add up and lash widens, a worn Valve Stem Seal can allow super hot oil to cook the exhaust valves. Timely replacement restores thermal balance, preserves compression, and maintains the acceleration that comes with the Mercury name prized by every Marquis owner. Automobile drivers say that after installing a Valve Stem Seal, the blue smoke disappears, gas mileage improves, and the emissions test is passed with ease. This gives your Mercury a second life. The parts market has come to appreciate the Valve Stem Seal ring profile due to the follower being designed for positive sealing and not an umbrella design. The reliability of the part is similar to major engine upgrades. Commuters rely on their Mercury Marquis to start clean and run smooth in everyday traffic. The unsung yet vital component quietly fulfills that promise.
