The weight of the M40 engine according to the catalog is 132 kg. The engine number M40 is located at the junction of the block with the oil pan. The most well-known problem of the engine is the accelerated wear of the camshaft lobes. The timing belt with the roller needs to be replaced every 40,000 km. In case of a valve failure, it bends. The injectors here quickly get dirty, causing the engine to start running rough and experiencing power loss. The usual cause of fluctuating RPM is an air leak, throttle body contamination, or faulty IAC valve. Due to the wear of the plastic flanges, the coolant level drops and the engine overheats.
