Disadvantages of the N62B48 engine
- Excessive oil consumption. When the engine travels over 100 thousand km, problems associated with increased oil consumption begin. The reason is damage to the valve stem seals and rings. Problems with the latter appear at 50-100 thousand kilometers.
- Instability of revolutions. The reason must be sought primarily in faulty ignition coils. Their complete replacement will be required. Another reason could be a flow meter, air suction system or valvetronic.
- Oil leak. As a rule, the problem manifests itself on the crankshaft oil seal. Sometimes the gasket on the generator housing deteriorates. Repair actions are reduced to their complete replacement.
The longer the motor is actively used, the more likely the catalysts are destroyed. During this process, their honeycombs penetrate the cylinders and cause scuffing. For this reason, it is recommended to completely remove them and install flame arresters. The correct approach to its maintenance helps to improve the operation of the unit and maximize its resource. Besides, you shouldn’t save on fuel and oil.
