- Until 1994, a nikasil coating was used, which is very afraid of sulfur in the fuel;
- From vibrations of the engine at idle, adjusting the valve timing often helps;
- The reason for the oil burner is in the valve stem seals or the crankcase ventilation system;
- The oil pump screws may loosen and fall into the sump, it is advisable to check them;
- Factory catalysts had a small resource and the owners got rid of them.
