Disadvantages of the Land Rover 508PN engine
- The atmospheric version is more reliable than a motor with a compressor and worries a little less often;
- The most famous problem is timing chain stretching closer to 100,000 km;
- Rarely, but sometimes there is a loss of intake or exhaust valve seats;
- The reason for floating engine speeds is most often the contamination of the throttle or injectors;
- Another weak point of the engine is the water pump and the ever-leaking heat exchanger.
