Disadvantages of the X20XEV engine

  • A simple and reliable engine rarely breaks down, but is repaired inexpensively;
  • From floating speed, cleaning either the idle speed controller or the crankcase ventilation system helps;
  • Sometimes the exhaust manifold cracks;
  • Relatively often, the camshaft position sensor fails here;
  • Monitor the condition of the timing belt, its resource is 60 thousand km, and when it breaks, the valves bend.

  1. Cynical Bastard

    The X20XEV is a horrible engine! Very unreliable and down on power in comparison to the older, but more sophisticated and more powerful C20XE “Red Top” engine.
