Suzuki J20B Engine Problems and Disadvantages
- High Oil Consumption: A common engine problem is high oil consumption due to piston ring seizure. This can lead to the need to replace the rings and other components of the piston group.
- Liner wear: A drop in oil level sometimes causes the liners to rotate, which may require a major overhaul.
- Timing chain: The timing chain does not have a high life expectancy and sometimes needs to be replaced before 150,000 km.
- Oil leaks: Leaks from under the valve cover and through the oil pressure sensor are common.
- No hydrocompensators: Since the engine is not equipped with hydrocompensators, it is recommended to adjust valve clearances every 90,000 km to maintain normal operation.
The Suzuki J20B engine is considered reliable and is capable of over 250,000 km with regular maintenance, although it requires special attention to oil levels and timely timing chain replacement.
