Valve Cover Foam Baffled Breather Grommet

The TRANS-DAPT Valve Cover Foam Baffled Breather Grommet (Part #6076) is a precision engine breather component engineered to manage crankcase ventilation while maintaining clean air separation. This 1-inch ID, 1.25-inch OD rubber grommet features internal foam baffle technology that traps oil mist and condensation before gases exit the breather system, preventing contamination of the intake charge and reducing carbon buildup in the combustion chamber.

Manufactured from durable black rubber with a 1.45-inch thickness, this breather grommet provides reliable sealing and acoustic damping at the valve cover connection point. The foam baffle design works passively—no moving parts, no maintenance—to separate liquid oil droplets from vapor before returning gases to the intake manifold. This is critical for extended engine life, as oil mist entering the combustion chamber increases deposit formation and reduces octane sensitivity. The compact form factor (2.7 x 1.4 x 3.6 inches) fits standard small-block and mid-sized engine applications across street and performance builds.

This component is essential for builders upgrading from stock breather setups or optimizing PCV systems for closed-loop, emissions-compliant operation. Applications range from street cars requiring cleaner intake air to carbureted engines where minimizing oil carryover directly improves fuel economy and plug life. The grommet serves as a drop-in replacement or upgrade element in custom valve cover breather assemblies, offering superior mist separation compared to simple tube-only designs.

TRANS-DAPT is recognized in the engine performance and restoration market for precision intake and crankcase ventilation components. This breather grommet represents engineered simplicity—a small part that makes a measurable difference in engine cleanliness and reliability when integrated into a well-designed PCV strategy.
