Keeping Your Intake Track Clean and Efficient

An oil catcher acts as an essential barrier between your crankcase ventilation and your engine's fresh air supply. By intercepting oily vapours before they can settle, this compact tank protects your clean air sensors and ensures your car burns fuel efficiently. Since this system directly alters how your engine manages recirculated air, it works together with other components to contribute to EGR system protection. If you’re servicing or upgrading your engine ventilation loop, it’s the perfect opportunity to also check your air filter, as crisp sealing ensures your ventilation pressure stays stable. Adding an engine oil catch tank is a proactive step that extends the life of your intake manifold and keeps your motor performing at its best.

Frequently Asked Questions

What is an oil catch tank?

An oil catch tank (or can) is an aftermarket filtration reservoir designed to catch oil mist, moisture, and unburnt fuel vapours passing through your engine’s Positive Crankcase Ventilation (PCV) system. Instead of allowing these contaminants to recirculate straight back into your intake manifold to be re-burnt, the car catch can traps the liquid residue securely inside its body, allowing only clean air to pass back out.

How does an oil catch can work?

An engine oil catch tank plumbs directly into the rubber air line running between the engine crankcase and the intake system. As high-pressure blow-by gases enter the tank, they pass through an internal mesh or baffled chamber. This structural barrier forces the heavy oil droplets and chemical moisture to condense out of the air suspension and pool harmlessly at the bottom of the reservoir, while the filtered air returns to the motor.

What are the signs you need an oil catch can?

The most obvious indicator is a drop in throttle responsiveness, erratic idling, or a persistent accumulation of wet, black oil residue inside your intake hoses. If you pull off your air ducting and find a puddle of oil coating the throttle body or if your vehicle often triggers sensor faults due to carbon blockages, your engine is suffering from excessive blow-by and requires an immediate car catch can installation.

What are the benefits of installing an oil catch tank?

Fitting an oil catch tank keeps your intake valves completely clean, eliminating the sticky carbon build-up that destroys engine performance. It also prevents oil mist from diluting your fuel octane rating, reducing the risk of dangerous engine knocking under load. What’s more, it extends the service life of your premium oil filter and other aftermarket engine parts by ensuring your entire internal combustion loop remains consistently free of sticky sludge.
