The 1.6-liter Opel Z16XER or LDE engine was assembled at different factories from 2006 to 2010 and installed on many popular concern models, such as Astra, Zafira and Insignia. This power unit was also installed on Chevrolet cars under its F16D4 index.
In 2005, the third generation of gasoline engines of the GM Family 1 family was introduced and one of its first representatives was a 1.6-liter engine for Opel cars. This is a fairly simple engine with multiport fuel injection, a cast-iron cylinder block, an aluminum 16-valve block head without hydraulic lifters, a timing belt drive, DCVCP phase shifters on two camshafts and a VGIS intake geometry change system.
The engine was installed on:
- Opel Astra H (A04) in 2006 – 2010;
- Opel Insignia A (G09) in 2008 – 2010;
- Opel Zafira B (A05) in 2008 – 2010.

Disadvantages of the Z16XER engine
- The first power units of this line were equipped with defective phase regulators, but they were replaced under warranty a long time ago, and now the main problems here are associated with contamination of the solenoid valve grids, which is why they simply jam.
- In second place, according to the complaints of the owners, is the ever-leaking oil heat exchanger, through which the lubricant seeps into the coolant, and vice versa, antifreeze dilutes the oil, and this greatly reduces the life of the oil pump and all liners in the engine.
- A capricious electrician delivers a lot of trouble, and this applies to all motors of the family. The engine ECU regularly fails, and usually the problem is in its connectors, and not in the board itself, often the electronically controlled thermostat or the ignition coil module fails.
- The weak points of the motor also include the membrane of the crankcase ventilation valve, which constantly bursts, forever leaking seals and the absence of hydraulic compensators. And do not forget to monitor the condition of the timing belt, because when it breaks, the valves bend.
