What Is an Oil Catch Can and Why Your Engine Needs One
An oil catch can is a smart, preventative upgrade that helps keep your engine clean by capturing oil vapors before they enter the intake system. This article explores how catch cans work, the types available, installation tips, and why they’re essential for long-term engine health.
What Is an Oil Catch Can?
An oil catch can is a small, sealed container that installs between the crankcase ventilation system and the intake manifold. As crankcase gases exit the engine, they pass through the can, which captures oil mist and blow-by contaminants in a filter or baffle. This prevents those particles from entering the intake system, where they can cause carbon buildup and performance loss over time.
There are various types of oil catch cans available, including baffled models that improve oil vapor separation, and PCV-specific units designed for daily drivers. Some are vehicle-specific, while others are universal and suitable for most engine types.
What Is the Purpose of an Oil Catch Can?
An oil catch can is a vital upgrade for vehicle owners who want to protect their engines and maintain peak performance. Its primary function is to trap excess oil vapor and contaminants from the PCV (Positive Crankcase Ventilation) system before they re-enter the intake manifold. This reduces carbon buildup, keeps the intake system clean, and promotes more efficient combustion. A properly installed oil catch can helps you maintain a more durable and cleaner engine over time.
Why You Might Need it？
Even in modern engines, oil vapor can bypass piston rings and enter the intake system. Over time, this results in:
-
Reduced engine efficiency
-
Carbon deposits on valves
-
Poor fuel economy
Installing an oil catch can or a PCV catch can is a proactive way to prevent these issues, especially in high-mileage or turbocharged engines.

FAQs
No, when properly installed, oil catch cans are safe and beneficial. They reduce contamination and improve engine longevity.
Yes. Especially in turbocharged, direct injection, or high-mileage engines, an oil catch can or PCV catch can helps prevent performance degradation.
Neglecting to drain it can lead to overflow, sending trapped oil back into the intake—defeating its purpose.
Check every 1,000 to 3,000 miles, depending on driving conditions and engine load.
Not directly. It prevents oil vapor from re-entering the intake, but doesn’t fix underlying oil consumption issues.
Typically, it's installed between the PCV valve and intake manifold. Some kits are bolt-on for specific vehicles.
Most catch cans have a drain plug at the bottom. Simply unscrew it and dispose of the contents properly.
