The device in question is an aftermarket component designed for specific automotive engines, particularly those prone to oiling issues due to their design or operating conditions. It functions by actively separating oil from the air that circulates within the engine’s crankcase. An example is its application in high-performance Subaru engines to mitigate oil starvation and related engine damage.
Its significance lies in its potential to enhance engine longevity and reliability. By efficiently removing oil vapor from the crankcase ventilation system, it helps prevent oil from accumulating in undesirable locations, such as the intake manifold or turbocharger. Historically, such systems have evolved from rudimentary catch cans to sophisticated units with internal baffling and filtration mechanisms, reflecting the increasing demands of modern engines.
