The weight of the AJ34 engine according to the catalog is 180 kg. The engine number AJ34 can be found on the cylinder block. The weak point of this engine is the unreliable VVT type variable valve timing regulators. The engine is made of aluminum and is prone to overheating, so please keep an eye on the cooling system. The VKG valve tends to get clogged quite quickly, leading to high oil consumption. When searching for the culprit of fluctuating RPM, it is worth starting with cleaning the throttle assembly. On high mileage, coolant leaks often occur due to burst hoses.
