The 1.3-liter carbureted Hyundai G4EA engine was produced in Korea from 1994 to 1999 and was installed only on the first generation of Accent models, and then only in some markets.
In 1994, the concern introduced a 1.3-liter carburetor unit of its own design. This was the first and last attempt by a Korean company to create an engine with such a fuel system. In its design, the engine was very reminiscent of Mitsubishi engines of the 80s of the last century: it has an in-line cast-iron cylinder block without any liners, a simple timing belt drive and an aluminum 12-valve cylinder head with a single camshaft, as well as hydraulic lifters.
Alpha family: G4EA, G4EH, G4EE, G4EB, G4EC, G4ER, G4EK, G4ED.

Disadvantages of the Hyundai G4EA engine
- All the main problems of this engine are associated with the vagaries of the Mikuni Solex carburetor, which not every service station can repair or simply correctly configure. A lot of trouble is thrown up by short-lived components of the engine ignition system.
- Another weak point here is not the highest resource of hydraulic lifters, sometimes they can knock already by a run of 80 thousand km and replacing them is quite expensive. The main reason is the drop in lubricant pressure due to wear of the oil pump plunger.
- According to the manufacturer’s official regulations, the timing belt changes every 60 thousand km, but there are reviews with a broken belt at a lower mileage, often with bent valves. The resource of the water pump in this motor is also small and it is better to replace them at the same time.
- Closer to 200,000 km, the engine usually already consumes oil up to 1 liter per 1000 km, and most often due to hardened valve stem seals. Replacing them is not very expensive. However, the cause is lying rings, then you can get by with just decarbonization.
- On specialized forums, owners complain about regular oil or antifreeze leaks, not the most reliable starter, strong vibrations due to wear of the power unit cushions, as well as sudden triggering of the emergency fuel shutdown mechanism.
