Disadvantages of the Y4 1.4 CiTD engine

  • Despite the modest displacement, this is a quite resourceful diesel engine;
  • The Siemens fuel system is reliable, but very afraid of airing;
  • Also, the PCV and VCV control valves on the high pressure fuel pump often fail here;
  • Carefully monitor the condition of the timing belt, or if it breaks, the valves will bend;
  • Other weak points of the engine include the crankcase ventilation membrane and the crankshaft damper pulley.
