The weight of the M270 engine according to the catalog is 137 kg. The M270 engine number is located at the junction of the block with the gearbox. Cracking of the phase regulators: In engines prior to 2014, the phase regulators quickly failed and started to crack, then they were updated and the problem started to manifest much later, but did not disappear completely. It does not have a high resource for the timing chain, usually it is replaced every 100-150 thousand km. Impulse disk displacement: In engines of this family, the impulse disk is pressed onto the camshaft and gradually shifts with each start. The process is especially accelerated by a stretched timing chain. This is the main reason for the starting problem of the engine, up to complete failure. Piston damage: In 2015, power units of this series received a different firmware and became more economical, however, immediately there were reports of replacing damaged pistons due to detonation. Poor quality fuel also significantly reduces the life of direct injection piezo injectors. Engine overheating: It is necessary to carefully monitor the condition of the cooling system of this unit, as the cylinder head heats up very quickly, even from a not very long overheating. This problem is exacerbated by the presence of an unreliable thermostat and water pump. Other breakdowns: Leaks often occur due to a stuck crankcase ventilation valve, as well as from the gasket of the heat exchanger or from the front crankshaft seal. Due to wiring breaks, the variable capacity oil pump valve hangs, fuel hoses leak, the turbocharger actuator gets stuck, and the adsorber quickly clogs.
