The weight of the R2 engine is 190 kg (with attachments). The engine number R2 is located at the junction of the block and the cylinder head. All issues with this simple and reliable diesel are associated with high mileage. The weakest point of the unit is considered to be the aluminum cylinder head. Cracks around the pre-chambers form at around 200,000 km, and it is not easy to buy another cylinder head. The timing belt is designed for 60,000 km, and if it breaks, the valves are often bent. Since there are no hydraulic compensators, the valves will need to be adjusted every 100,000 km.
