Engine Overview and Common Failures

The weight of the LF1 engine according to the catalog is 185 kg. The serial number of the LF1 engine is located at the joint between the block and the gearbox. The main problem with the engine is the temperamental direct fuel injection system. If the high-pressure fuel pump fails, gasoline will enter the lubrication system and the engine will seize. It is important to monitor the cooling system as the gasket can quickly blow out during overheating. Like all engines with direct injection, it is prone to carbon buildup on the valves. Throttle body cleaning and adaptation are also often necessary.
