An oil catch can is for stopping harmful engine buildup. It collects extra oil and moisture vapors that would otherwise go back into the engine’s combustion chamber.
This is how it works:
- Gases from the crankcase go through the can.
- Oil, fuel, and water particles are filtered out.
- The filtered gases are sent back to the intake manifold for combustion.
This leads to cleaner air/fuel mixture and lower emissions.
An oil catch can prevent the collection of bad stuff. This helps the engine to stay in top performance and last longer.
Pro Tip: Check and empty the catch can every once in a while. This stops buildup and makes sure it works correctly.
What is an Oil Catch Can?

Oil catch cans are essential for vehicles on the road. They capture oil that could build up in the engine intake manifold and damage it. This article will show different types of oil catch cans and their purpose.
How Can an Oil Catch Work?
An oil catch can is a device to stop too much oil from entering the combustion engine. It catches the oil mist created during combustion and separates it from the air-fuel mixture.
It’s attached to the engine’s crankcase ventilation system. Oil droplets come into contact with baffles and filters inside the catch can. These separate them from the air, causing them to thicken.
The coagulated oil drops to the bottom of the can, ready for disposal. Catching the oil droplets before they enter the engine helps prevent the buildup of carbon deposits. Plus, it reduces emissions and improves fuel economy.
Benefits of Installing an Oil Catch Can
An oil catch can is an aftermarket accessory for cars. It catches oil vapors and stops them from getting into the intake manifold. This can cause sludge buildup, which reduces performance.
Here are some of the benefits of installing an oil catch can:
- Keeps Engines Clean: It prevents oil from building up in the intake manifold and air induction system.
- Improves Performance: Blocking oil residue from entering the engine helps keep the engine efficient and working well.
