Air/Oil Separator Small Body - Corvette 14-17

The MOROSO Air/Oil Separator Small Body for Corvette 2014–2017 is a compact crankcase ventilation solution engineered to manage blow-by gases and prevent oil carryover in high-performance LS-based engines. This aluminum separator removes oil mist from crankcase vapors before they enter the intake manifold, protecting fuel mixture quality and reducing carbon buildup on intake valves—critical considerations for forced-induction and heavily modified engines where standard PCV systems fall short.

With a 2.125-inch diameter body standing 4.5 inches tall, this separator is sized specifically for tight engine compartments found in C7 Corvettes. The 3/8-inch NPT female inlets and outlets accept standard braided hose and AN fittings, allowing flexible routing around fuel rails, alternators, and other underhood components. The black anodized aluminum construction resists corrosion and integrates seamlessly with performance intake systems. Installation requires basic plumbing skills and an understanding of proper PCV routing to avoid creating positive pressure in the crankcase.

This separator is ideal for Corvette owners running increased boost levels, extended track sessions, or aggressive fuel mapping where factory ventilation becomes a limitation. Separated oil returns to the pan via gravity or a dedicated return line, while clean vapors proceed to the intake or atmosphere depending on system design. Properly configured, an air/oil separator extends engine life, improves consistency on the dyno, and eliminates the oil consumption issues common in modified LS engines operating outside factory parameters.

MOROSO is a recognized manufacturer of engine ventilation and fuel system components for street and race applications. Their separators are purpose-built for specific engine families rather than universal designs, ensuring fitment and performance on intended platforms. The small-body variant suits stock and mildly modified C7 engines; larger MOROSO units address more extreme displacement and boost applications.
