Disadvantages, breakdowns and problems B3
Most often, problems with the ignition system are discussed on specialized forums.
In the version with hydraulic compensators, saving on oil leads to their failure.
Another weak point of the motor is the oil pump pressure relief valve.
The timing belt is designed for about 60 thousand km, but if the valve breaks, it does not bend here
On long runs, oil consumption is often found in the region of a liter per 1000 km
