Disadvantages of the Land Rover 508PN engine
The atmospheric model worries a little less frequently and is more dependable than a motor with a compressor;
The most well-known issue is timing chain stretching that approaches 100,000 kilometers;
Loss of intake or exhaust valve seats occurs infrequently but occasionally; throttle or injector contamination is the most common cause of floating engine speeds;
The water pump and the constantly leaking heat exchanger are two more engine weak points.
