Self-Draining Oil Catch Can

The Spelab Oil Catch Can is a high-efficiency solution engineered for Dodge Ram 5.9L and 6.7L diesel engines (2003-2025) that are equipped with aftermarket valve covers. Its primary function is to capture oil vapor and blow-by gases from the crankcase ventilation (CCV) system, preventing these contaminants from entering the intake manifold. This helps maintain intake cleanliness, reduce carbon buildup, and improve overall engine longevity, making it ideal for modified or performance-tuned trucks. Constructed from durable billet aluminum with a CNC-machined finish, this catch can is available in red or black anodized options to complement your engine bay aesthetics. A key benefit is its self-draining design, which uses the engine block's OEM side port for automatic oil return, eliminating the need for frequent manual emptying and reducing mess. Installation involves connecting the catch can to the valve cover and routing the collected oil via a downward hose for proper drainage. It is important to note that this catch can is not compatible with trucks equipped with dual alternators. It is not compatible with trucks equipped with dual alternators.
