Valve Cover Breather w/ Slant Edge - Alm Blue

The Ford Valve Cover Breather with Slant Edge in Aluminum Blue is a direct-fit crankcase ventilation component engineered for Ford small-block applications requiring a 1-1/4 inch breather hole. This push-in design integrates the raised Ford oval logo and slant-edge profile to manage crankcase pressure while maintaining factory aesthetics. The aluminum construction with blue paint finish resists corrosion and complements OEM engine bay appearance on vehicles where proper crankcase breathing is critical for engine longevity.

Crankcase breather design directly affects blow-by management—excessive pressure compromises gasket seals and accelerates oil degradation. This Ford breather's slant-edge geometry optimizes airflow direction while the aluminum body provides thermal stability under engine bay conditions. At 0.38 lbs and compact dimensions (3.9 x 2.7 x 5.9 inches), the unit mounts cleanly without interference on tight engine bays. The push-in retention system ensures secure seating in the 1-1/4 inch mounting hole without additional fasteners, simplifying installation and future service intervals.

Ford small-block owners performing engine rebuilds, carbureted conversions, or fuel-injection retrofits rely on proper crankcase ventilation components to prevent pressure buildup that degrades ring seals and oil condition. This breather serves both stock restorations and performance builds where factory-correct appearance matters. Whether managing carburetor applications or modern fuel-injected engines, this component ensures consistent crankcase evacuation and maintains the integrity of cylinder sealing during varying load conditions. Part number 302-436 is the OEM Ford specification for this application.
