The valve and hose of ventilation of a case are located in a cover of a head of the block of cylinders. On release cars till 2001 they are established in a sealing ring on a cover of a head of the block of cylinders (fig. 2.46) . On release cars since 2001 they are screwed on the left side of a cover of a head of the block of cylinders (fig. 2.47) .

Remove the valve of ventilation of a case. On release cars till 2001 extend it from a sealing ring. On release cars since 2001 remove from the valve a hose, turn out the valve and again put on it a hose.

Get the engine. On frequency of idling by a finger check vacuum existence on the valve. In the absence of vacuum check serviceability of the valve and a hose condition. For check of the valve disconnect from it a hose. At a valve purge from outside which the valve fastens to a head cover, the valve should pass air freely. At a valve purge on the other hand the valve should pass insignificant amount of air hardly. Otherwise replace the valve.
