Valve Cover Breather

The Valve Cover Breather from EDELBROCK is an essential component for serious engine builders and daily drivers alike. As a mechanic, you know that proper crankcase ventilation is non-negotiable—excessive pressure buildup inside the crankcase accelerates gasket failure, forces oil past seals, and compromises engine longevity. This breather assembly eliminates those problems by allowing controlled venting while preventing atmospheric moisture and contaminants from entering the engine. Whether you're running a stock rebuild or a modified stroker, this upgrade belongs on your short list.

EDELBROCK's valve cover breather uses a direct-fit design that integrates seamlessly with most conventional valve covers without requiring custom fabrication or extensive plumbing modifications. The assembly incorporates a baffle or separator element that breaks up oil mist and allows vapors to vent while containing splash-back, keeping your bay cleaner and reducing oil consumption. Compact at just 3.65 x 2.7 x 5.65 inches and weighing only 0.27 lbs, it adds negligible bulk to your engine bay while delivering genuine functional benefit. The robust construction and proven EDELBROCK engineering mean this breather will outlast multiple engine rotations without performance degradation or maintenance headaches.

This breather is ideal for street engines, race applications, and high-boost setups where crankcase pressure spikes demand reliable venting. Installation typically takes minutes on most American V-block engines—verify your valve cover fitment and outlet port size before purchase to ensure compatibility with your specific application. Pair this with quality PCV plumbing and you'll notice improved ring seal efficiency, extended oil change intervals, and elimination of the telltale oil seepage that plagues older builds. For enthusiasts serious about engine health and longevity, the Valve Cover Breather from EDELBROCK is a no-compromise upgrade.
