Moroso 85605 PCV Air/Oil Separator Catch Can - Billet Aluminum, Black Anodized

The Moroso 85605 PCV Air/Oil Separator is a billet aluminum catch can designed to intercept excess crankcase vapors and oil mist before they re-enter your engine's intake tract. Stock PCV systems route these vapors directly back into the intake manifold, which can lead to detonation, reduced performance, and oil deposit buildup on intake valves and runners. This separator solves that problem by capturing the oil mist inline, keeping combustion chambers and intake components clean.

This unit features a two-piece billet aluminum body that simply unscrews for easy draining — no mess, no tools required. The black anodized finish gives it a clean appearance right out of the box, while the aluminum construction makes it suitable for polishing, chrome plating, or powder coating to match any custom engine bay build.

Key Features:

• Plumbed inline with the vehicle's PCV system to capture crankcase vapor and residual oil mist
• Prevents oil deposits from forming on intake valves, runners, and manifold surfaces
• Also effective at collecting excess moisture produced by ethanol-enriched fuel combustion
• Two-piece billet aluminum body unscrews for quick, clean oil draining
• Black anodized finish — can also be polished, chromed, or powder coated
• Includes 1/2" 90° inlet and outlet fittings, 31" of 1/2" rubber hose, and a billet aluminum mounting clamp

The Moroso 85605 is a straightforward, high-quality upgrade for performance engines where intake cleanliness and consistent combustion are a priority.
