Engine Overview and Common Failures
The weight of the K6A engine assembly is 70 kg. The K6A engine number is located at the junction with the gearbox. The turbine has a short lifespan. Many engine modifications are equipped with IHI or less commonly Hitachi turbines, and they rarely last more than 50,000 km when not properly maintained. Regular oil changes and allowing the engine to idle after a trip are necessary. Another common issue with this engine is blown head gasket. Keep an eye on the cooling system, pump, and electric fan. According to the maintenance schedule, the timing chain should be replaced every 90,000 km, but for active drivers, especially those with a turbo, it tends to stretch earlier. It may also cause valve interference. After reaching mileage over 150,000 km, the piston rings start to stick, resulting in increased oil consumption. Decarbonization is often ineffective, and ring replacement is required. Other known issues include frequent detonation when using 92 octane gasoline in hot weather, lubricant leaks from seals, and the tensioner bearing for the auxiliary belt may seize up. Don't forget to adjust the clearances, as valve burning is a common occurrence.
