Crankcase Evac System w/ Billet Push-In Breathers

The Crankcase Evac System w/ Billet Push-In Breathers from MOROSO (MPN 68866) is a precision engine ventilation solution designed for high-performance and modified engines. This system is ideal for street rods, race cars, and serious automotive enthusiasts who require reliable crankcase management under demanding conditions.

Engineered to control crankcase pressure and prevent oil blow-by, this weld-on evacuation system extends engine life, improves ring seal integrity, and reduces oil contamination. It features billet aluminum push-in breathers that enhance flow characteristics and provide a professional appearance compared to standard rubber grommets. The kit includes all necessary components, such as breathers, check valves, fittings, and mounting hardware, to create a complete evacuation circuit.

Street rod builders, engine builders, and turbocharged enthusiasts will benefit most from this comprehensive evacuation package, especially those running custom engine combinations. The system accommodates a 5/8-inch diameter hose, compatible with most aftermarket piping systems, and its weld-on design allows for secure mounting directly to the block or pan for maximum reliability during aggressive driving.
