4x4 Catch Cans

Aftermarket 4x4 catch cans are designed to capture the oil that gets into the crankcase and is fed back into the motor. When this happens, the contaminants are burnt in the combustion process, creating blow-by gas.

When the blow-by gas combines with oil vapour, it creates a sticky build-up that coats your valves and injectors, resulting in a noticeable decrease in fuel efficiency and performance.

This build-up can be significantly reduced with 4x4 catch cans. Simply install them between the crankcase ventilation system and the air intake and blow-by gas will be redirected through a filter, which separates the oil from the air. Oil is then caught in the catch can, making sure the air from the crankcase is clean before it is fed back into the intake. 

Fitting 4x4 catch cans to your turbo diesel vehicle is particularly important because of high engine compression ratios that increase the amount of blow-by gas.
