The 1.0-liter Opel Z10XEP or LJ4 engine was produced from 2003 to 2009 in Austria and was installed only on the third and fourth generations of the Corsa model or the very first Agila. The motor was distinguished by the presence of a proprietary system for changing the geometry of the Twinport intake tract.
Differs in the presence of a proprietary system for changing the geometry of the intake tract Twinport, which closes half of the intake valves, which is why the engine pulls better at the bottom. At high rpm, the flaps open and the motor runs at full speed. Controls the motor of the Bosch ME7.6.1 / Bosch ME7.6.2 ECU.
The engine was installed on:
- Opel Agila A (H00) in 2003 – 2007;
- Opel Corsa C (X01) in 2003 – 2006;
- Opel Corsa D (S07) in 2006 – 2009.

Disadvantages of the Z10XEP engine
- most of the problems arise from the electrical, weak wiring and ECU are to blame;
- low resource and the timing chain, it may require replacement up to 150,000 km;
- very often the dampers of the Twinport system are seized and the EGR valve is overgrown with carbon;
- owners often contact the service to replace the thermostat and oil pump;
- the source of an oil leak is usually a pressure sensor and only replacement will help.
