Hot gases direct through an oil separator (126) in a cover of a head of the block of cylinders and via the pipeline (140) in soaking-up branch pipes. In an oil separator (126) oil is filtered and flows through a retsirkulyatsionny pipe (127) back to a head of the block of cylinders.

The valve of adjustment of pressure in a cover of a head of the block of cylinders prevents emergence in the engine of too high depression.

For ventilation of space of a membrane in the valve of adjustment of pressure in a cover of a head of the block of cylinders the ventilating opening (shooter) is provided. It should not be littered with dirt or preservatives.
