PCV System: Description
The crankcase ventilation system recycles crankcase vapors back into the intake system for reburning. The system consists of an oil separator and necessary connecting hoses. Orifices are also used in the hoses to meter the amount of crankcase vapors being recycled into the intake system.
In addition, Fuego Turbo models use a vacuum regulating check valve, and a one-way check valve located on intake manifold.
