The Honda 12342-RYE-004 PCV Valve Grommet is a genuine OEM sealing grommet designed for the PCV (Positive Crankcase Ventilation) valve on select Honda automotive engines. This molded rubber grommet provides a tight, leak-free seal between the PCV valve and the valve cover, preventing oil leaks, air intrusion, and crankcase pressure issues. Engineered from high-quality, heat- and oil-resistant material, it maintains durability under extreme engine temperatures and long-term exposure to oil vapors. Replacing a worn, cracked, or hardened grommet ensures proper PCV system function, improves emissions performance, and helps maintain smooth engine operation.
