An oil catch can mitigates this by capturing the oil before it reaches the turbo or the intercooler, preventing blockages and maintaining the efficiency of the forced induction system. Over time, this leads to carbon buildup, which disrupts the smooth airflow required for efficient combustion and can result in rough idling or decreased power.

Additionally, regular maintenance of the catch can—emptying the collected oil and cleaning the unit—provides an opportunity to inspect the condition of the engine's internal components through the contaminants trapped inside. How Blow-by Affects Engine Performance Combustion events force gases past the piston rings into the crankcase, a phenomenon known as blow-by.
This process effectively removes the oil from the recirculating air, keeping the combustion chamber cleaner. The baffling creates turbulent flow, forcing the droplets to collide and merge into larger particles that are easier to capture.
Oil Catch Can vs Mesh Filter: Which Offers Better Blow-by Protection
Its primary function is to capture oil mist and contaminants that escape past the piston rings and into the blow-by gases before they can cycle back through the engine. Choosing the Right Unit for Your Vehicle When selecting a catch can, consider the filtration media and the total capacity of the unit.
