What are the common issues with the 4g63 engine?
2 Answers
4g63 engine's common issues include weak cylinder block thermal load capacity, limited potential for specific power output improvement, and poor aluminum corrosion resistance. An engine is a machine that converts other forms of energy into mechanical energy. Engines can refer to either power generation devices or the entire machine including power units, with types including internal combustion engines, external combustion engines, gas turbines, and electric motors. The maintenance method for the 4g63 engine involves cleaning the air filter: The air filter is directly related to the engine's air intake during vehicle operation. If the air filter becomes clogged or accumulates excessive dust, it will restrict engine airflow and allow large amounts of dust to enter the cylinders, accelerating carbon buildup.
I've been driving Mitsubishi cars for over a decade and know the 4G63 engine inside out. This engine is notorious for burning oil, especially when the piston rings wear out severely - you'll see blue smoke from the exhaust. The valve stem seals aren't durable either, typically needing replacement after 150,000 km. Turbo models are worse, with the crankcase ventilation valve prone to clogging, causing the turbo intake pipe to fill with oil. In summer, the coolant temperature always runs high - my car has blown head gaskets three times due to aging. Now I have to check the oil every 5,000 km and keep a close eye on the radiator, otherwise it might surprise me with an unexpected repair anytime.
