Air Oil Separator System

If you want to start racing your direct-injection turbocharged car on a regular basis, you will do well to get an air oil separator here at CarMods Australia for your car.

Oil separators help to separate the oil in your vehicle’s crankcase from blow-by. Blow-by is the air that leaks past your engine’s piston rings into your crankcase under pressure. Because turbocharged engines have more engine-cylinder pressure than naturally aspirated engines, they tend to have more blow-by; that pressure is even greater during performance driving. Your engine’s crankcase is also pressurized when driving, so the blow-by is bound to mix with the oil within it. Most vehicles use catch cans to remedy this, but catch cans only prevent the buildup of such aerated oil inside your engine's intake manifold. Oil separators go a step further; they separate the oil from the blow-by and reroute the oil back into your car’s oil system.     

Other benefits you get when you buy an air oil separator for your car at CarMods Australia include deterring oil recirculation in your engine cylinders and preventing detonation in engine parts other than the cylinders.
