Chevy Tahoe PCV & Breather Components

A positive crankcase ventilation system (PCV) belongs to emission control systems that pretty much every modern fuel-burning automobile has at its disposal. Emission control devices are implemented in the air intake, exhaust, and the engine assembly itself to minimize the impact on nature caused by the operation of the internal combustion engine. The PCV and breather provide the ventilation of engine crankcase, i.e. remove the exhaust fumes from there in an eco-friendly manner and prevent the pressure in the crankcase from increasing to abnormal levels. A malfunctioning PCV or breather may not only degrade the eco-friendliness of the engine, but also cause some damage to its components and affect its performance. For instance, excessive pressure can push out oil seals and lead to motor oil leaks or high oil consumption.
