Check and replacement of the valve of system of operated ventilation of a case (PCV) (each 48 000 km of run or time in 24 months)
The PCV system provides a conclusion of karterny gases via the special valve on a hose back in the inlet pipeline, from where they arrive in chambers of combustion and are burned out during normal functioning of the engine. The system consists a hose going from a cover of a head of cylinders to the inlet pipeline and a hose of supply of fresh air, laid between an air purifier and a cover of a head of cylinders.
The PCV valve with the hose connected to it is planted in the inlet pipeline under the fuel highway, or is in a back part of the engine, depending on model (see illustrations below).
