An oil catch tank works and functions like a crankcase vent filter.
In most vehicles, the vented gas and oil are recycled back into the vehicle air intake piping just before the throttle body; an oil catch tank will bypass the connection between the crankcase and air induction intake piping.
This will help in relieving the pressure placed against the valve train under severe engine loads. Unlike other crankcase filters (literally a small cotton gauze filter), the Oil Catch Tank will prevent oil dripping onto adjacent engine components.
The tank will catch or collect excess engine oil that is vented out by the valve train. This will ensure a clean engine compartment and maintain the custom look of the engine and maximizes engine performance at the same time.
