The weight of the BTR engine according to the catalog is 255 kg. The BTR engine number is located at the front, at the junction of the block and the cylinder head. It is a very reliable diesel engine and problems with it only occur at high mileage. The modern fuel system with piezo injectors cannot tolerate poor quality fuel. If you pour anything into the tank, soon you will be faced with a repair cost of up to 500,000 rubles. Saving on lubrication significantly reduces the lifespan of the turbine and hydraulic compensators. After 200-250 thousand km, the timing chain may need to be replaced, which is quite expensive.
