Disadvantages of the Land Rover 406PN engine
This engine is performing well in terms of reliability, but fuel consumption is not promising;
The primary issues in this case are caused by an odd and unreliable timing chain;
In addition to the EGR tube frequently cracking here and the crankshaft rear oil seal sweating, high mileage frequently necessitates repairing both cylinder heads with the replacement of all valves.
