Check for engines with long service life is especially important. If deterioration too big it is necessary or to replace directing valves (only in a workshop) or to replace a head of cylinders.

Deposit adjournment on directing valves remove by means of development for cleaning.

Insert the new valve. The end face of a core of the valve should not leave from directing.
The prevention
Owing to various diameters of cores use inlet valves only in inlet directing, and final valves – only in final.

By the indicator of linear moving measure value of moving of a plate of the valve at it качании.
Deterioration border: directing the inlet valve – 1,0 mm, directing the final valve – 1,3 mm.

At большем value of moving replace directing valves in a workshop.
