The weight of the Z16XEP engine according to the catalog is 120 kg. The engine number Z16XEP is located at the junction of the block and the gearbox. Drivers often complain about the motor's power losses due to Twinport system failures. Less frequently, the clogged EGR valve is to blame for the unstable operation of the power unit. The timing belt should be changed at 150,000 km, but it is better to do it more often, as a broken valve can cause damage. The ECU block, thermostat, and ignition module also have a low service life. There are no hydraulic compensators, and the valve clearances need to be adjusted every 100,000 km.
