Engine Overview and Common Failures

The weight of the C30A engine assembly is 195 kg. The engine number C30A is located at the junction of the block and the gearbox. The main issue with the engine is oil consumption, which can occur up to 100,000 km. It is very important to monitor the lubrication level, even a slight decrease can be dangerous. Sometimes it is possible to get away with just replacing the lifters, but often the camshafts are also replaced. The timing belt is renewed every 90,000 miles, and if it breaks, it always bends the valves. The weak points of the engine include the short-lived catalytic converter and ignition coils.
