Disadvantages of the Mitsubishi 4G93 engine

  • GDi modifications are known for the frequent vagaries of the direct fuel injection system;
  • The problem of all versions of the motor is the rapid failure of hydraulic lifters;
  • When the idle speed controller is dirty, the engine starts to stall on its own;
  • On runs of more than 150 thousand km, an oil burn usually begins due to the occurrence of rings;
  • If you miss the oil level, then the likelihood of the liners turning is very high.
