The weight of the Z12XE engine according to the catalog is 100 kg. The engine number Z12XE is located at the junction of the block and the gearbox. The main issues with the motor are related to electrical glitches, usually resulting in ECU failure. The timing chain rarely lasts more than 100,000 km, after which it stretches and begins to rattle. The EGR valve frequently becomes clogged with carbon deposits and the exhaust manifold cracks. The thermostat and oil pump do not have the most outstanding lifespan here. The use of cheap oils quickly affects the condition of the hydraulic compensators.
