Serial production of Z22SE engines began in 2000. This unit replaced the 2-liter X20XEV and was a joint development of General Motors, ITDC, GM Powertrain and SAAB. The final tuning of the engine was already worked on in Britain, in the Lotus Engineering Corps.
In various modifications, the internal combustion engine was installed on almost all General Motors models of that time. Officially, the Z22 line of motors went as “Ecotec Family II Series” and were produced at once at 3 factories – in Tennessee (Spring Hill Manufacturing), in New York (Tonawanda) and in German Kaiserslautern (Opel plant).
In Germany and England, the engine was designated as – Z22SE. In America it was known as – L61 and was installed on a number of Chevrolet, Saturn and Pontiac cars. Under license, the Z22SE was also installed on Fiat Croma and Alfa Romeo 159.

Features of Z22SE operation
The problems of the Z22 line are common to all Opel engines of the time.
- Timing drive.
- Antifreeze in candle wells.
When a diesel sound appears in the Z22SE engine, there is a high probability of failure of the hydraulic timing chain tensioner, which usually jams every 20-30 thousand kilometers. The chain drive on the Z22SE is generally one of the most problematic components of this unit.
- Large motor resource.
- Possibility of tuning.
