Pcv Grommet/Oil Baffle 1pk

The Moroso PCV Grommet/Oil Baffle (SKU MOR68772) is a precision-engineered component designed for positive crankcase ventilation (PCV) systems in performance and street engines. This single-pack rubber grommet serves as both a mounting interface and oil baffle, managing blow-by gases while preventing oil carryover into the intake system. Whether you're rebuilding a classic engine, upgrading a modern performance build, or maintaining an existing PCV setup, this baffle grommet is essential for proper crankcase pressure regulation and engine longevity.

Constructed from durable rubber compound, the PCV grommet features a 0.75-inch inner diameter (ID) and 1.25-inch outer diameter (OD), with a 1.5-inch thickness that provides secure retention and reliable sealing. The integral baffle design effectively separates oil mist from crankcase vapors, allowing gases to exit while trapping liquid contaminants before they enter the intake manifold. This baffle function reduces oil consumption, minimizes carbon buildup in the intake, and protects downstream components from contamination. The robust rubber material withstands engine bay temperatures and pressure cycles while maintaining a consistent seal over time.

Engine builders, restoration specialists, and performance enthusiasts rely on Moroso PCV components to ensure proper crankcase breathing on both naturally aspirated and forced-induction engines. Installation involves pressing or sliding the grommet into the valve cover or PCV block passage, where it acts as both a spacer and filter element. Its compact 3.75 x 1.55 x 4.95-inch package makes it suitable for tight engine bay spaces. This single-unit offering is ideal for custom builds, replacements, or OEM-equivalent upgrades where quality and fit are non-negotiable.
