The 2.0-liter Opel X20XEV or Ecotec L34 engine was assembled from 1994 to 2000 in Germany and was installed on the vast majority of mid-size models of the concern of its time. After a major update in 1998, a new ECU and balancer shafts appeared in the engines.
The X20 series also includes engines: X20SE, X22SE, X22XE, X25XE and X30XE.
The engine was installed on:
- Opel Astra F (T92) in 1996 – 2000; Astra G (T98) in 1998 – 2000;
- Opel Calibra A (C89) in 1994 – 1997;
- Opel Omega B (V94) in 1994 – 1999;
- Opel Vectra A (J89) in 1994 – 1995; Vectra B (J96) in 1995 – 2000.

Disadvantages of the X20XEV engine
- A simple and reliable engine rarely breaks down, but is repaired inexpensively;
- From floating speed, cleaning either the idle speed controller or the crankcase ventilation system helps;
- Sometimes the exhaust manifold cracks;
- Relatively often, the camshaft position sensor fails here;
- Monitor the condition of the timing belt, its resource is 60 thousand km, and when it breaks, the valves bend.
The X20XEV is a horrible engine! Very unreliable and down on power in comparison to the older, but more sophisticated and more powerful C20XE “Red Top” engine.
Crankshaft sensor failed all the time
