WCS Autotecnica GM1416931 PCV Valve Grommet Replacement

The WCS Autotecnica GM1416931 is a direct-fit replacement PCV valve grommet designed to restore proper crankcase ventilation on compatible General Motors vehicles. A cracked, hardened, or missing PCV valve grommet allows unmetered air to enter the intake system, disrupting the air/fuel ratio and causing rough idle, increased oil consumption, and failed emissions tests.

Key Features:

• Restores crankcase ventilation: Allows blow-by gases to safely vent back into the combustion chamber
• Improves engine performance: Evacuates unburned gasoline vapors from the crankcase into the intake manifold, restoring proper air/fuel ratio
• OE-matched dimensions: Manufactured to original equipment grommet dimensions for a hassle-free, drop-in installation
• Heat and oil resistant materials: Grommet compound is engineered to withstand intense engine heat and continuous exposure to vaporized engine oil
• ISO/TS 16949 quality standard: Produced in strict accordance with ISO/TS 16949 Quality Management System specifications
• 2-Year / Unlimited Mileage Warranty: Backed by a comprehensive warranty for long-term confidence
