Valve Cover Grommet Set

The Mr. Gasket Valve Cover Grommet Set (Part No. 6376) is a precision rubber breather and PCV grommet kit designed for engine block installation and crankcase ventilation systems. This valve cover grommet set accommodates a 1.22-inch hole diameter and comes as a complete kit, eliminating the need to source individual components when repairing or upgrading your engine's ventilation integrity.

Constructed from durable black rubber, these grommets provide reliable sealing and vibration isolation where the breather or PCV line passes through the valve cover or engine block. The rubber formulation resists oil degradation and thermal cycling, maintaining elasticity under the temperature and pressure variations typical of engine operation. At just 0.1 pounds and measuring 4 x 1.45 x 6 inches, the kit ships compactly while delivering all hardware needed for installation. Mr. Gasket's OEM-compatible design ensures fitment with standard 1.22-inch apertures found across domestic and import engine platforms.

This grommet set addresses a critical but often overlooked maintenance point: preventing oil seepage and crankcase vapor leaks at ventilation penetrations. Worn or missing grommets allow unfiltered air ingress and oil loss, compromising engine cleanliness and efficiency. Whether you're rebuilding a classic engine, addressing a PCV system overhaul, or replacing aged rubber on an existing build, the Mr. Gasket valve cover grommet set delivers proven reliability at a straightforward price point. Sourcing OEM-quality components individually is both time-consuming and costly; this kit consolidates everything into a single, verified package.
