Catch Cans

A catch can is an oil separator installed between the engine's crankcase ventilation outlet and intake. Crankcase gas can carry oil mist back into a diesel engine's intake, where it can combine with soot from the exhaust gas recirculation system. Deposits can then build up through the intake tract. The rate and severity vary with the engine, vehicle use, condition and servicing history.

A ProVent catch can passes crankcase gas through filter media that separates captured oil before the gas returns to the intake. It is intended to reduce further oil contamination. It does not remove deposits already inside the engine or guarantee a particular power, economy or service-life result.

Direction Plus ProVent catch can kits are configured for specific vehicle applications. Depending on the listing, a kit can include the catch can, bracket, hoses, fittings and associated hardware. Correct application selection matters because mounting points, hose routing and available under-bonnet space differ between vehicles.

KEY CATEGORIES AND WHAT THEY'RE BUILT FOR

WHY FIT A CATCH CAN TO A MODERN DIESEL

The main purpose is intake cleanliness. Reducing the oil mist entering the intake can limit one part of the deposit-forming mixture found in many exhaust gas recirculation equipped diesel engines. This can be particularly relevant to vehicles used for towing, touring, regular load carrying or extended operation.

A catch can should still be treated as one part of an engine management and servicing approach. It does not replace correct engine oil, scheduled maintenance, fault diagnosis or cleaning where deposits already exist. Any benefit will depend on the engine's condition, installation quality and ongoing servicing of the unit.

VEHICLE-SPECIFIC KITS WE STOCK

All active products in this collection are supplied under the Direction Plus vendor. Current ProVent catch can listings cover Land Cruiser 70, 200 and 300; Prado 120, 150 and 150/155; Hilux N70; Fortuner and Hilux; Amarok; Holden Colorado; Jeep Wrangler; and Land Rover Defender 110.

The catalogue also includes applications for Ranger, Everest and BT-50; Ranger PXIII bi-turbo; D-Max, MU-X and BT-50 from 2020 on; Challenger and Triton; Triton and Pajero Sport; Navara D40 and NP300; and Nissan Patrol. A universal ProVent Ultimate kit is also listed, but universal fitment requires closer assessment of space, mounting and hose routing.

CHOOSE BY USE CASE

For a vehicle-specific installation, start with the exact make, model, engine and production details requested on the product page. Similar model names do not guarantee the same bracket or hose arrangement.

For a Land Cruiser 70 build where both listed components are required, compare the PreLine-Plus and ProVent combination product with the catch-can-only options. For a universal installation, confirm mounting space, connection sizes and routing requirements before ordering.

A fuel manager kit, breather kit and catch can perform different functions and should not be treated as interchangeable names. If the correct system or combination is unclear, speak with the workshop before purchase. This avoids selecting a product that does not address the intended part of the vehicle.

WHAT A QUALITY CATCH CAN INSTALLATION INVOLVES

Installation starts with the correct bracket and stable mounting position. The original crankcase ventilation path is then rerouted through the catch can in accordance with the vehicle-specific instructions. Hoses must be kept clear of heat, moving parts and abrasion points, with enough allowance for engine movement.

The drain also needs to remain accessible for inspection and emptying. Connections should be secured, routing checked and the completed system inspected for leaks while the engine is running. Poor routing or an incorrect kit can create fitment and servicing problems even when the catch can itself is suitable.

SERVICING THE CATCH CAN

Captured liquid needs to be checked and drained as required. The amount collected varies with the engine, its condition and how the vehicle is used. Inspect the system regularly, follow the manufacturer guidance supplied for the applicable product and replace the filter element when that guidance requires it.
