Engine Overview and Common Failures
The weight of the J24B engine assembly is 130 kg. The engine number J24B is located at the junction of the block and the gearbox. Cracks in the block. In the first two years of production, defective cylinder blocks were frequently encountered, often with cracks in the cooling jacket and coolant entering the lubrication system. The manufacturer replaced the engines under warranty, but you can still come across such an engine. Cracks in the cylinder head. The second most common problem is cracking of the cylinder head due to overheating, so it is necessary to carefully monitor the cleanliness of the cooling system radiator. Such a problem is especially common on power units from the early years of production. Low chain lifespan. Despite the fact that the timing chain is designed for the entire engine service life, it often stretches to 150,000 km mileage, sometimes even earlier. Usually, the camshaft phaser needs to be replaced together with the chain, which doubles the cost of repair. Other drawbacks. There are also regular complaints on forums about excessive oil consumption due to piston ring sticking, quickly hardening seals and oil control valve seals, as well as frequent lubricant leaks. It is advisable to check the valve clearances and condition of the spark plugs every 30,000 km.
