If you're serious about maintaining your vehicle’s performance and longevity, an oil catch can should be at the top of your upgrade list. While often overlooked, this small yet powerful device prevents harmful oil vapors and contaminants from re-entering your engine’s intake system. Whether you own a turbocharged performance car, a naturally aspirated daily driver, or even a high-mileage workhorse, an oil catch can is a crucial addition.
At Demon Pro Parts, we know the importance of keeping your engine clean and running at its best. That’s why we offer high-quality oil catch cans designed to protect your engine and optimize its efficiency. Let’s dive into why installing an oil catch can is one of the best investments you can make for your vehicle.
What Is an Oil Catch Can and How Does It Work?
During normal combustion, small amounts of gases escape past the piston rings into the crankcase, a process known as blow-by. These gases contain oil vapors, carbon deposits, and other contaminants. The vehicle’s Positive Crankcase Ventilation (PCV) system is designed to reroute these gases back into the intake manifold to be burned again. However, this can lead to a variety of performance and reliability issues.
An oil catch can is installed between the PCV system and the intake manifold. As gases pass through the catch can, oil droplets and contaminants are trapped in a reservoir instead of entering the intake. This keeps your intake valves, throttle body, and manifold clean, ensuring your engine runs more efficiently.
Why an Oil Catch Can Is Essential
1. Prevents Carbon Buildup on Intake Valves
Modern direct-injection engines are particularly prone to carbon buildup because they lack fuel injectors that spray onto the intake valves. Over time, oil vapors stick to the intake valves, forming a layer of carbon deposits. This restricts airflow, reduces fuel atomisation, and leads to power loss, misfires, and decreased fuel efficiency. An oil catch can captures these oil vapors before they reach the valves, keeping them clean and reducing the risk of performance degradation.
2. Improves Throttle Response and Fuel Economy
A contaminated intake system can disrupt airflow and affect the air-to-fuel ratio, leading to poor combustion. This can cause hesitation, sluggish throttle response, and increased fuel consumption. By keeping the intake system clean, an oil catch can ensures a consistent and smooth airflow, improving throttle response and maximizing fuel efficiency.
3. Reduces the Risk of Engine Knock and Pre-Ignition
Oil vapors entering the combustion chamber can lower the octane rating of your fuel. This increases the likelihood of pre-ignition or engine knock, which can cause serious engine damage over time. High-performance and turbocharged engines are especially vulnerable to knock, making an oil catch can a vital addition for reliability.
4. Protects Turbocharged Engines
Turbocharged engines generate higher levels of blow-by due to increased cylinder pressures. Excess oil mist can coat the intercooler, intake pipes, and throttle body, reducing the efficiency of the turbo system. A high-quality oil catch can prevents oil from contaminating these components, keeping your turbo system operating at peak efficiency.
5. Extends the Life of Your Engine
Over time, excessive oil deposits can lead to sludge buildup, clogged intake components, and even premature wear of internal engine parts. By removing harmful contaminants before they can cause damage, an oil catch can helps extend the life of your engine, saving you money on costly repairs and maintenance.
6. Keeps Your Spark Plugs Cleaner
When excess oil vapors reach the combustion chamber, they can coat the spark plugs, leading to fouling and misfires. This results in poor combustion, rough idling, and decreased fuel efficiency. A clean-burning engine performs better, and an oil catch can helps prevent unnecessary spark plug fouling.
7. Reduces Exhaust Smoke and Emissions
If too much oil is burned in the combustion chamber, it can result in excessive blue or gray smoke from the exhaust. This not only affects performance but also increases emissions. An oil catch can minimizes oil consumption, helping your engine run cleaner and reducing its environmental impact.
How to Maintain an Oil Catch Can
An oil catch can is not a set-it-and-forget-it component. Regular maintenance is key to ensuring it functions properly.
✔ Check and Drain Regularly – How often you need to drain the catch can depends on your vehicle and driving conditions. For daily drivers, draining it every 3,000 to 5,000 miles is recommended. For high-performance or turbocharged vehicles, check it more frequently.
✔ Inspect for Clogs – Over time, the catch can’s filter element can become saturated with oil and contaminants. Make sure it’s clean and free of blockages.
✔ Use a High-Quality Catch Can – Not all catch cans are created equal. Demon Pro Parts offers high-performance oil catch cans designed with superior filtration and durable construction to ensure maximum efficiency and reliability.
