Disadvantages of the Rover 18K4K engine

  • The main problem with this engine is that it is very afraid of overheating;
  • Therefore, here it not only often breaks through the cylinder head gasket, but also simply leads the head;
  • And don’t forget to change the long and expensive head bolts every time you remove it;
  • The timing belt is designed for 100,000 km of run, and when it breaks, the valves always bend;
  • The weaknesses of the motor also include short-lived supports and ignition coils.
