Disadvantages of the Suzuki G13BA engine

  • The main troubles of the owner here are connected with the vagaries of the outdated power supply system;
  • This aluminum unit is also very afraid of overheating, and especially its cylinder head;
  • After 150,000 km, an oil burner often appears due to wear on the valve stem seals;
  • Many problems are caused by unreliable components of the engine ignition system;
  • Since there are no hydraulic lifters, the valves need to be adjusted every 30,000 km.
