Disadvantages of the ET3J4 engine

  • A generally reliable engine often worries about trifles, especially about electrics;
  • Many problems are caused by regular failures of the components of the ignition system;
  • Engine speed floats due to a dirty throttle or idle speed controller;
  • The timing belt is designed for 80 thousand km, but its rollers may not pass that much;
  • Any overheating here leads to suffocation of the valve stem seals and burning oil.
