Car Air Oil Separator Systems

An air oil separator can help to keep blow-by oil from getting sucked back into your engine. We at Car Mods Australia have a wide range of air oil separators and water oil separators for sale that can solve your engine’s blow-by issues effectively. In addition to our oil separator systems, we have over 300,000 automotive products of other kinds in stock, all developed with the needs of Australia’s vehicles in mind.    

Blow-by can be defined as the gases in an engine’s combustion chambers (air, fuel, and moisture) that escape past its piston rings and into its crankcase. These gases escape when the piston rings aren’t well sealed or not a good fit; they are also bound to escape when your engine’s cylinder walls widen and pistons become smaller with age and wear. All petrol or diesel-oriented engines have some level of blow-by, but performance-car engines tend to have more because of the higher engine loads they have to handle. As the pressurized blow-by rushes through your engine’s crankcase, it picks up oil vapor from the oil in the crankcase. Because most street-legal cars are designed to reroute engine blow-by back into their inlet manifolds, that oil vapor can end up building up on the walls of your car intake manifold and engine cylinders. When that happens, the oil can cause improper detonation and the lowering of your fuel’s overall octane rating. Also, by coating the air intake, the oil can clog airflow into the engine.

Our oil separator systems are designed to prevent that. They channel the oil-infused blow-by through condensing material that separates the oil from the gases. They then drain the oil into the engine’s oil pan while venting the cleaned air out to the atmosphere or back to the engine’s air inlet pipe.
