- Because of this, catalysts are quickly destroyed, and their crumbs lift up the engine cylinders.
- It often squeezes out paper oil channel gaskets under the front cover.
- The timing chain does not differ in resource either, it is often replaced already by 200,000 km of run.
- Also, the motor is very afraid of overheating, and the water pump does not last very long here.
