Engine Overview and Common Failures

The weight of the Z14XEP engine according to the catalog is 105 kg. The engine number Z14XEP is located at the junction of the block with the gearbox. The most common problem here is the constantly sticking throttle valves of the Twinport system. The timing chain can stretch and start rattling at a mileage of up to 150,000 km. The cause of fluctuating RPM and loss of power is often a clogged EGR valve. The source of oil leaks is usually the oil pressure sensor and the valve cover. The oil pump, thermostat, and ECU control unit have a relatively low lifespan here.
