Disadvantages of the 5M-EU engine

  • A well-known problem of power units of this series is a breakdown of the cylinder head gasket;
  • Often, owners overtighten the bolts in the head, trying to get rid of oil leaks;
  • The reason for floating speed here is usually contamination of the throttle or idle valve;
  • The remaining engine failures are most often associated with the vagaries of the ignition system;
  • Since there are no hydraulic lifters, the valves require periodic adjustment.
