DeatschWerks Oil Catch Can Assembly 0.5L & 1L

DeatschWerks Oil Catch Can Assembly 0.5L & 1L

DeatschWerks Oil Catch Can Assembly 0.5L and 1.0L is a universal oil vapor separation can designed to be installed in the engine crankcase ventilation circuit, either as a vented configuration or as a recirculated configuration. In a typical PCV or breather system, blow by gases carry suspended oil vapor and droplets. This assembly adds a dedicated separation volume and internal media so oil can condense and be collected in the can rather than continuing downstream in the ventilation plumbing.

Compared with factory ventilation routing that can return vapor directly to the inlet tract, a dedicated catch can is used when the installer wants a serviceable collection point for condensed oil and contamination. This assembly is offered in two capacities to support packaging constraints and service interval preferences. DeatschWerks also documents that the 1.0 liter size is commonly required by many motorsports sanctioning bodies.

Internally, the can uses stainless mesh and baffled plates to promote separation. Externally, the body is anodized 6061 T6 aluminum. The mounting approach incorporates a clockable bracket that allows the inlet and outlet orientation to be rotated through 360 degrees to simplify hose routing in tight bays. Fluid level can be checked with the included dipstick, and the base includes an integrated drain port intended for plumbing or periodic draining.

Installation and use considerations: because this is a universal assembly, vehicle specific hoses, fittings, and mounting location are installer defined. DeatschWerks specifies that the assembly can be plumbed vented or recirculated, and the bracket clocking feature is intended to reduce compromises in hose routing. Like any serviceable catch can, periodic inspection and draining are required, and routing choices should maintain appropriate crankcase ventilation function for the intended use.
