Engine Overview and Common Failures
The weight of the VAZ-341 engine according to the catalog is 130 kg. The VAZ-341 engine number can be found in two places. The early diesel engines had weak pistons that often broke down at 50,000 km. Then the pistons were updated and now cars with mileage of over 200,000 km can be found. The unit is equipped with a Bosch distributor-type injection pump, which has minimal issues. Pay close attention to the condition of the timing belt, as its breakage can cause valve damage. The glow plug block and fuel filter electric heater often fail. There are no hydraulic lifters here, and the valve clearances need to be adjusted every 30,000 km. However, the main problem with the engine is its rarity and the scarcity of quality spare parts.
