Engine Overview and Common Failures

The weight of the Z10XEP engine according to the catalog is 85 kg. The engine number Z10XEP is located at the junction of the block and gearbox. The most common problems are related to the electrical system, caused by weak wiring and the ECU unit. The timing chain has a relatively low lifespan and may require replacement before reaching 150,000 km. The throttle valves of the Twinport system often get stuck here and the EGR valve gets clogged with carbon deposits. Owners frequently seek service for thermostat and oil pump replacement. Oil leakage is usually caused by a faulty pressure sensor and can only be resolved through replacement.
