The crankcase ventilation filter is one of the only components of the crankcase ventilation system, and is therefore an important piece in maintaining the functionality of the system. The crankcase vent filter works the same way as any other filter.

The crankcase filter performs the extremely important function of equalizing the pressure in the crankcase during differtent operational phases of the engine. At times, air needs to be released from and at the other times, to be sucked into the crankcase. This is necessary, as excessive crankcase pressures can cause oil leaks to form if allowed to build too high.
