Disadvantages of the Rover 11K4F engine

  • This unit is very afraid of overheating and its gasket breaks quite often;
  • There are wet sleeves in the motor, at high mileage they often sag and crack;
  • And therefore, the main problem of the engine is mixing grease with antifreeze;
  • Once every 100 thousand km, do not forget to change the belt or if it breaks, the valves will bend;
  • Weaknesses also include short-lived and at the same time very expensive engine mounts.
