Engine Overview and Common Failures

The weight of the VAZ 2103 engine according to the catalog is 121 kg. The engine number of the VAZ 2103 is located above the oil filter. Wear of the camshaft Owners of all engines in the VAZ classic series face wear of the camshaft. The reason is usually due to the neglect of valve adjustment or cost-cutting on maintenance. Engine overheating The thermostat, water pump, and electric fan also have a very modest lifespan, which often leads to engine overheating with gasket failure and even cracks in the cylinder head. High oil consumption On high mileage, oil consumption usually appears and increases sharply. The cause of this is worn oil control rings, piston rings, or a clogged PCV system. Other problems The weak points of this engine include a temperamental carburetor, short-lived timing chain and auxiliary equipment, as well as frequent leaks from seals or under the valve cover.
