Catch cans, also known as oil catch cans or crankcase ventilation filters, are aftermarket devices used to separate and collect oil vapor and other contaminants from the crankcase ventilation system of an internal combustion engine.

In modern engines, blow-by gases containing oil mist and other byproducts are generated during the combustion process. These gases, if not properly managed, can accumulate and lead to carbon buildup, reduced engine efficiency, and potential performance issues.

Catch cans are designed to intercept these blow-by gases before they can re-enter the intake system. They typically consist of a chamber with baffles or filter media that allow the gases to pass through while capturing and condensing the oil and contaminants. The collected oil is then stored in the catch can, preventing it from circulating back into the engine.

More About Vehicle Catch Cans

By installing a catch can, engine performance and longevity can be improved. The separation of oil and contaminants reduces the potential for carbon deposits on the intake valves, which can cause reduced airflow and decreased engine efficiency over time. It also helps maintain cleaner intake components and reduces the risk of oil fouling in the combustion chamber.

Catch cans are particularly beneficial for engines that operate under high-stress conditions, such as turbocharged or supercharged engines, where blow-by gases are more prevalent. They are commonly used in performance-oriented vehicles, as well as in applications where oil contamination can be a concern, such as in modified or high-mileage engines.

Regular maintenance of catch cans is necessary to ensure proper functionality. This involves periodically draining and cleaning the collected oil and monitoring the condition of the filter media or baffles, replacing them as needed.
