A Positive Crankcase Ventilation (PCV) hose is an essential component of a car's emission system. The PCV system is responsible for recycling oil fumes and other gases from the engine back into the combustion chamber to burn off and reduce emissions. The hose runs between the PCV valve and the intake manifold of the engine.

Without the PCV hose, the engine would not perform optimally, and the emissions would be higher. The hose helps maintain the engine's condition by regulating the pressure inside the engine and preventing the buildup of gases that could cause damage. Over time, the PCV hose can wear out, crack, or become clogged, which can lead to engine performance issues and increased emissions. It is essential to have the PCV hose inspected regularly and replaced if necessary to ensure the car runs smoothly and efficiently.
