Moroso 85669 Air-Oil Separator PCV Catch Can Kit Small Body

The Moroso 85669 Air-Oil Separator is a small body PCV catch can kit designed to intercept excess crankcase vapors and residual oil mist before they can re-enter your engine's intake tract. By plumbing inline with your vehicle's PCV system, this separator acts as a barrier against the contaminants that factory ventilation systems route directly back into the intake manifold.

From the factory, crankcase vapors and oil mist are recirculated into the intake manifold — a design compromise that can lead to detonation, accelerated carbon buildup, and oil deposits on intake valves and runners. The Moroso 85669 eliminates this problem by capturing those contaminants in a dedicated reservoir before they reach the intake.

Key Features:

• Small body design — compact 4.5" tall × 3.75" diameter (with clamp) fits in tight engine bays where larger separators won't
• Billet aluminum construction with internal baffling and cleanable mesh media for efficient oil mist capture
• Polished billet aluminum finish complements any engine compartment; can be chromed, powdercoated, or anodized for a custom look
• Bottom drain with elbow allows virtually mess-free draining of collected oil without removing the unit
• Two-piece body unscrews easily for cleaning and maintenance

Kit Includes:

• 3/8" N.P.T. 90° inlet and outlet fittings
• 60" of 3/8" diameter rubber hose for inline plumbing
• Billet aluminum mounting clamp
• Stainless steel mounting bracket

The Moroso 85669 is part of Moroso's proven Air-Oil Separator lineup, trusted by performance enthusiasts and racers alike to protect engines from the harmful effects of oil contamination in the intake system.
