Valve Cover Breather Kit Push-In Fits 1.22 Hole

The Valve Cover Breather Kit Push-In Fits 1.22 Hole by MOROSO is a critical ventilation component designed for engine builders and performance enthusiasts who need reliable crankcase pressure relief. Excessive blow-by gases and pressure buildup inside an engine's crankcase can damage seals, compromise performance, and reduce engine longevity. This breather kit solves that problem by providing a clean, efficient path for those gases to exit safely while preventing oil mist from entering the intake system.

Built from durable steel with a chrome finish, the Valve Cover Breather Kit features a round 1.5-inch outer diameter tube that directs crankcase vapors away from critical engine components. The kit includes a push-in adapter or grommet sized for a 1.22-inch hole installation, ensuring a secure fit without requiring tools or clamps. MOROSO's reusable design and steel construction provide years of reliable service in both street and high-performance applications, while the chrome finish resists corrosion and maintains a polished appearance under the hood.

This breather kit is ideal for custom engine builds, racing applications, and any vehicle running a modified or supercharged engine where stock ventilation is insufficient. Installation is straightforward thanks to the included push-in grommet—simply insert it into your 1.22-inch valve cover hole and attach the breather tube. The compact dimensions and lightweight design make it suitable for tight engine bays, while the reusable construction ensures long-term value and easy maintenance for shops and hobbyists alike.
