• Billet aluminum body with polished finish and ball-milled top for a show look

The Polished Aluminum Round Ball Milled Push-In Breather with PCV Valve combines a dress-up breather cap with a built-in PCV valve in one piece, so crankcase ventilation and PCV routing are handled from a single valve cover opening. Billet aluminum construction with a polished finish and ball-milled top style gives the engine bay a machined, custom look, while the integrated 90° PCV valve with a 3/8" hose barb inlet supports proper PCV hose routing.

This unit is sized to a 1" neck and pushes into compatible valve cover ventilation openings — neck or inlet sizing must match the valve cover grommet, hose, or opening style for proper fitment. It's commonly used on universal hot rod, muscle car, truck, and performance builds, including Chevrolet, Ford, and Chrysler V8 applications with matching valve cover openings.

Before installation, verify neck diameter, grommet size, PCV routing, and valve cover opening style, along with clearance around the rocker cover, coil, and hood.
