Disadvantages of the Land Rover 406PN engine

  • With reliability, this engine is doing well, but fuel consumption is not encouraging;
  • The main problems here are delivered by an unusual and not very reliable timing chain;
  • On high mileage, it is often necessary to repair both cylinder heads with the replacement of all valves;
  • Also, the EGR tube regularly cracks here and the crankshaft rear oil seal sweats.
