— official information
- High oil consumption. After the engine reaches a mileage of one hundred thousand km, it often has an increase in oil consumption. The reason for this is hidden in the worn valve rings and seals. You need to replace them.
- Instability in the number of revolutions. A symptom of a rhythm disturbance in the operation of the unit is often associated with a violation of the functionality of the ignition coils. We need to install new ones. The following malfunctions can also be the cause of this ailment – air pumping, broken valvetronic or flow meter.
- Oil is leaking. The most commonly affected crankshaft oil seal, as well as the generator case seal gasket. Disassembly of these units and replacement of gaskets will be required.
- Seizure in the cylinder. The main reason is the smallest particles that got inside from the catalyst that collapses over time. You can fix the problem by replacing them with flame arresters.
It is possible to increase the durability of the engine and reduce the number of minor breakdowns if it is inspected and maintained on time, and not to save on fuel and oil.
