Ford Ford Victoria-Marquis American 1998-2012

To me, the vapor (PCV valve or ventilation valve of the auxiliary box) for my Ford Crown Victoria and Marquis models from 1998 to 2012 and manufactured in America is the small part that regulates the flow of oil vapors and unburned gases from inside the engine (the auxiliary box) to the intake manifold to be burned again, instead of leaking into the atmosphere. The importance of this lies in its being the primary responsible for reducing environmental pollution and preventing pressure buildup inside the engine, as well as maintaining internal engine cleanliness and preventing the formation of harmful deposits. The high quality of corrosion-resistant metal and the tight internal spring ensure reliable operation and controlled flow of gases without clogging or leakage. Replacing the damaged, stuck, or blocked one restores engine pressure balance, reduces oil consumption, and immediately eliminates any white smoke from the exhaust, engine vibrations, or oil accumulation in unnatural places, so your car operates cleanly and efficiently. **Specifications** - Compatible models: Ford Crown Victoria 1998 – 2012, Marquis 1998 – 2012 - Part name: Vapor (PCV valve) - Country of manufacture: America - SKU number: 3W7E-6K817-US
