During the engine operation, it is necessary to clean the gas recirculation system during periodic maintenance work

Resinous deposits accumulate in the ventilation system parts, which reduce the passage of gases into the atmosphere.

As a result, the increased gas pressure inside the engine crankcase causes gases to break through together with the oil through the seals and oil seals.

To perform the work, you will need: an 8 mm socket head, pliers, a container for washing, gasoline.
