The weight of the M10 engine according to the catalog is 130 kg. The M10 engine number is located at the junction of the block and the gearbox. The most well-known problem is that the cylinder block tends to crack over time. Often, the cracks affect the cooling jacket and antifreeze gets into the oil. The second most common engine failure is accelerated wear of the camshaft lobes. Engines with high mileage suffer from erosion of main and connecting rod bearings. The mechanism for adjusting the valve clearances quickly fails.
