Air/Oil Separator - Small Body

The Air/Oil Separator - Small Body from Moroso is an essential component for any engine that routes crankcase vapors through a PCV system, particularly in modified or high-performance applications where excessive blow-by occurs. This separator effectively removes oil mist and liquid contaminants from pressurized crankcase gases before they enter the intake manifold, preventing carbon buildup, valve fouling, and intake contamination.

Moroso's small-body design utilizes proven internal baffle technology to separate oil particles from vapor through centrifugal and gravitational principles, allowing reclaimed oil to drain back to the pan while clean vapor exits through the outlet port. The compact footprint—measuring 7.4 x 4.5 x 13.7 inches and weighing just 2.97 lbs—fits tight engine bays without sacrificing separation efficiency, making it ideal for retrofits or custom builds where space constraints are common.

Mechanics and performance enthusiasts favor Moroso separators for various applications, including LS swaps and any build where PCV efficiency directly impacts longevity and reliability. This separator is designed to enhance engine performance by reducing harmful contaminants, ensuring consistent operation across extended highway runs or track sessions.
