The crankcase breather filter, also called a crankcase vent filter (CCV), is part of a vehicles crankcase ventilation system. This filter is a part of the crankcase ventilation system in internal combustion engines of a relatively small number of vehicles including vintage\/muscle cars, race cars, and motorcycles. But it’s found on others including diesel engines such as the Dodge Cummins.<\/p>\n
As the engine runs, its pistons push gases into the crankcase. These gases cause a build-up of pressure that robs the engine of its operational power. The purpose of the crankcase system is to enhance the relieving of this pressure, as it releases excess gas to the environment or reroutes it back to the engine. <\/p>\n
The gases released may contain some debris, oil particles, and other contaminants, requiring the need for the crankcase breather filter. Let\u2019s take a closer look at how this vital component works and what to do when it malfunctions.<\/p>\n
