The weight of the M271 engine according to the catalog is 160 kg. The engine number M271 is located at the junction of the block with the gearbox. The most well-known problem of the engine is the sticking of the exhaust valves due to carbon deposits. The second most common issue is the unreliable timing chain, which can stretch up to 100,000 km. This is followed by frequent oil leaks from the oil filter housing or heat exchanger. The crankcase gas ventilation system quickly becomes clogged, causing the pipes to burst. Fuel entering the oil is considered a trademark defect of EVO series engines.
