What Are Oil Catch Cans?
If you have ever looked inside your intake and saw that it was coated with oil, there is a solution for that. An oil catch can is installed within the crankcase ventilation system to separate oil vapors and contaminants from the air before they are returned to the intake system. By capturing oil mist and condensation, a catch can helps keep the intake tract, intercooler, and engine components cleaner while improving long-term engine reliability.
Why Should I Have an Oil Catch Can for My Engine Setup?
Modern engines, especially turbocharged applications, generate crankcase vapors that often contain oil particles. Without a catch can, these contaminants can accumulate in the intake system, intercooler, and intake valves. Installing an oil catch can reduces this buildup and helps maintain cleaner airflow throughout the engine.
For performance and boosted applications, it's almost a must as this can improve long-term reliability and simplify maintenance. Especially if the original engine was not designed for boost. If you are adding a turbocharger or any other type of forced induction to a naturally aspirated engine, you need a catch can.
In an extreme example, high performance engine applications require their catch cans to be drained multiple times over just a weekend of intense driving. Cars that run high octane fuel or ethanol mixed with higher boost levels or compression ratios have to empty their catch cans every few times they get on track.
What Makes the BOOST Catch Cans so good?
BOOST Products oil catch cans are designed specifically with performance and motorsport applications.
They combine high flow capacity with effective oil separation, helping to remove oil mist while maintaining proper crankcase ventilation. Their robust construction, compact design, and high-quality materials ensure long service life even in demanding environments.
Whether used on a street car, race car, or custom engine build, BOOST Products catch cans provide reliable performance and high-grade quality.
What Is the Difference in Oil Catch Cans?
Not all oil catch cans are created equal.
Basic catch cans often function only as collection tanks, while more advanced designs incorporate internal baffles, chambers, or separation media to improve oil separation efficiency.
The effectiveness of a catch can depends on its internal design, airflow management, capacity, and overall build quality.
Choosing the right catch can ensures effective oil separation without restricting crankcase ventilation.
What's Important to Know About Oil Catch Cans?
Proper installation is critical for maximum performance.
The catch can should be installed within the crankcase ventilation system and sized appropriately for the engine's airflow requirements. Regular inspection and draining are recommended, especially on high-performance or turbocharged engines.
A properly designed catch can helps reduce oil contamination within the intake system while maintaining efficient crankcase ventilation.
