Mopar 53022142AB PCV Seal | Genuine OEM Gen 3 HEMI Positive Crankcase Ventilation Grommet

The Mopar 53022142AB PCV Seal is a genuine OEM replacement component designed to provide a proper seal between the positive crankcase ventilation (PCV) valve assembly and the valve cover on select Gen 3 HEMI engines. Although small in size, the PCV seal plays a critical role in maintaining a properly functioning crankcase ventilation system by preventing vacuum leaks, oil seepage, and unmetered air from entering the engine. Over time, exposure to engine heat, oil vapors, and repeated thermal cycles can cause rubber seals to harden, crack, or lose their elasticity, potentially resulting in drivability concerns, oil residue accumulation, or check engine lights. Replacing a worn seal with a genuine Mopar component helps restore factory sealing integrity while ensuring your HEMI engine continues to operate efficiently and reliably.

The PCV system is responsible for evacuating blow-by gases from the crankcase and redirecting them back into the intake tract where they can be burned during combustion. Proper operation of this system is especially important on modern high-performance engines, including naturally aspirated and supercharged Gen 3 HEMI applications. A compromised PCV seal can allow unmetered air to enter the intake system, disrupting fuel trims and negatively affecting idle quality, throttle response, and overall engine performance. For enthusiasts running aftermarket cold air intakes, upgraded superchargers, catch can systems, or custom calibrations, maintaining an airtight PCV system becomes even more important to preserve tuning consistency and engine efficiency.

The Mopar 53022142AB seal is manufactured to the same specifications as the original factory-installed component, ensuring a precise fit and long service life. Unlike many generic replacement seals that may vary in dimensions or material quality, genuine Mopar parts are engineered specifically for HEMI applications and tested to meet OEM durability standards. During routine maintenance, valve cover servicing, PCV valve replacement, or engine rebuilds, replacing the seal is an inexpensive preventative measure that can help eliminate future vacuum leaks and oil-related issues before they become larger concerns.

Whether you’re refreshing an aging daily driver, servicing a dedicated drag car, or maintaining a high-horsepower Hellcat build, attention to seemingly minor components often contributes significantly to overall reliability. Small sealing components frequently experience the harshest operating conditions within the engine compartment, making proactive replacement a smart investment. By choosing a genuine Mopar PCV seal, enthusiasts and professional technicians alike can be confident they are installing a component designed to maintain factory performance standards while supporting long-term engine health.

The Mopar 53022142AB PCV Seal is an ideal replacement for owners seeking OEM-quality fitment and dependable sealing performance.
