Engine Overview and Common Failures

The weight of the M157 engine according to the catalog is 220 kg. The engine number M157 is located at the junction of the block and the gearbox. This unit is often subjected to tuning and its lifespan depends on the degree of forced induction. Like almost all engines with aluminum-silicon coating, it tends to develop scuffs. The wear of the oil pump gear is often the catalyst for this problem. The short-lived timing chain system and particularly the tensioners also cause a lot of trouble here. Another weakness of the engine is the quite delicate piezoceramic injectors.
