The MANN-Provent 200 Catch Can kit from Western Filters offers good value for money and is an easy DIY fit with minimal tools. But one question I often get asked is what are the benefits of installing Catch Can.
I have an MY23 Isuzu DMax X-Terrain and installed a MANN-Provent 200 Catch-Can kit right from day one. One of the best things about the kit Western Filters put together is that it contains everything required for the installation and has clear instructions.
The mounting bracket locates neatly between the brake master cylinder and air-filter housing. Notably, it uses all the Isuzu factory body screw location points; there is no need to drill additional holes in the bodywork.
Benefits of a Catch-Can
Fitting a Provent 200 Catch-Can to an Isuzu D-Max can provide several benefits. Here are some of the advantages:
- Reduced oil contamination: The Provent 200 Catch-Can helps to separate oil vapour from the crankcase gases before they enter the intake system. This prevents oil mist from accumulating in the engine, reducing oil contamination and carbon build-up on internal components such as intake valves, turbocharger, and intercooler. It helps to keep the engine clean and running efficiently.
- Extended engine life: By reducing oil contamination and carbon build-up, the Provent 200 Catch-Can helps prolong the engine’s life. It prevents excessive wear on critical engine parts and maintains optimal engine performance over time.
- Improved Fuel Efficiency: Another significant advantage of a Catch-Can is its positive impact on fuel efficiency. When oil vapours and contaminants are allowed to enter the intake system, they can mix with the air-fuel mixture, affecting the combustion process. This interference can result in incomplete combustion, reduced power output, and increased fuel consumption. By capturing these substances before they reach the intake system, a Catch-Can ensures a cleaner air-fuel mixture, leading to more efficient combustion. As a result, the engine can generate more power with less fuel, improving overall fuel efficiency. This benefit is particularly valuable for 4×4 diesel vehicles, known for their high fuel consumption due to their heavier weight and off-road demands.
- Enhanced turbocharger performance: Turbocharged engines benefit from a Catch-Can installation as it helps to prevent oil contamination of the turbocharger. By keeping the turbocharger clean, it can maintain its efficiency and performance, resulting in improved power delivery and responsiveness.
- Preservation of Performance: Four-wheel drive diesel vehicles are often utilised for towing, hauling, or navigating challenging terrains. These demanding applications can exert additional stress on the engine, potentially leading to increased oil contamination and carbon build-up. By installing a catch can, drivers can preserve the performance of their diesel engines, ensuring consistent power delivery over time. The cleaner combustion environment facilitated by the Catch-Can helps maintain optimal engine performance, preventing power loss and maintaining torque levels even under strenuous conditions. Consequently, fitting a catch can is an investment that enables 4×4 diesel enthusiasts to maximise their vehicle’s potential and enjoy peak performance.
- Reduced emissions: The Provent 200 Catch-Can traps harmful contaminants, including oil, before they get recirculated back into the engine. This helps to reduce emissions, contributing to a cleaner environment and potentially ensuring compliance with emissions regulations.
Fitting a catch can to any modern 4×4 diesel vehicle brings many benefits. The advantages are substantial, from promoting engine longevity and reducing maintenance costs to improving fuel efficiency and preserving performance. Moreover, Catch-Cans contribute to environmental sustainability by reducing harmful emissions. However, it’s important to note that the specific benefits may vary depending on the condition of your engine, driving style, and other factors. Additionally, it’s recommended to follow the manufacturer’s instructions and consult with professionals to ensure proper installation and compatibility with your Isuzu D-Max model.
Judging by the dirty oil we collected from the Catch-Can after the first 5000 kilometres, our investment is already paying dividends.
The drain hose doubles as the collection and storage receptacle for the dirty oil. Consequently, it’s worth ensuring you run the longest hose possible to guarantee adequate storage capacity from one service to the next.
I wrapped the drain tap in a piece of rubber and secured it with cable ties; this kept it clean and free from mud and road grime. I also placed a few lengths of spiral wrap around the drain hose to protect it from debris, but I allowed a few gaps to provide windows to see the see oil level.
After 5000 kilometres, I collected approximately 60 millimetres of contaminated oil.
