Engine Overview and Common Failures

The weight of the engine R18A according to the catalog is 105 kg. The engine number R18A is located at the junction of the block and the gearbox. The power unit is quite sensitive to the quality of the fuel and oil used. Poor gasoline quickly affects the condition of the catalyst or lambda sensors. Owners often complain about the very noisy operation of the adsorber valve on the forum. Engine mounts and timing belt tensioner have a modest lifespan here. There are no hydraulic compensators, and approximately every 50,000 km the valves need to be adjusted.
