The dry weight of the G4EK engine ranges from 101.3 to 107.9 kg. The G4EK engine number is located at the front, at the junction of the block and the cylinder head. Unstable operation: In the early years of production, there were many problems with assembly quality and some components, but they were later resolved and now most complaints are related to fluctuating RPM due to a dirty throttle and oxygen sensor, as well as engine wear due to a cracked coil. Hydraulic lifters: Another weakness of this engine is the low lifespan of the hydraulic lifters. There are different theories on the causes: some blame manufacturing quality, others attribute it to poor oil, and thirdly, a drop in lubrication pressure in the system due to rapid wear of the oil pump plunger. Timing belt failure: Quite a number of Alpha family engines have failed due to timing belt breakage, as the recommended replacement interval of 60,000 km is somewhat optimistic. It often breaks earlier. It is advisable to also replace the water pump along with the belt, as its lifespan is also not very long. Oil consumption: Oil consumption in such power units occurs at mileages ranging from 100,000 to 200,000 km, and this greatly depends on the quality of maintenance and the operating conditions of your vehicle. Usually, oil consumption can be reduced by replacing the oil seals or rings. Other drawbacks: Weak points also include unreliable auxiliary equipment, weak engine supports, regular leaks of lubricant or coolant, and ECU glitches due to the exhaust flex pipe being burnt out. If the engine does not start, check the emergency fuel cutoff mechanism.
