Opel Signum 2005 2.0-16V Turbo engine Z20NET
Engine reliability and common problems:
The engine is identical to Saab B207L engine. It features an aluminum alloy block with cast iron liners and a chain-driven timing system without variable valve timing.It has two balance shafts with a separate chain. The engine is overall reliable. Around 200,000 km, replacing the timing chain and the balance shaft chain often becomes necessary. Replacing two chains, tensioners, gears, and guides involves significant costs. Symptoms like knocking, rattling, and ticking noises, especially during a cold start, indicate potential chain issues. If the timing chain is not replaced in time, metal shavings can appear, leading to bearing damage and clogged oil channels. In severe cases, the stretched chain can skip, bending the valves and requiring an extensive engine overhaul.The turbocharger is durable overall, but its wastegate valve frequently fails, requiring attention. Another common issue is the short lifespan of the PCV system valve, which often needs replacement.
The crankshaft position sensor is a vulnerable component. Its failure can prevent the engine from starting or cause it to stall while driving. However, replacing the sensor is straightforward.
Overall, this engine can last around 260,000 to 430,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.

| Timing chain change interval | 200,000 km (recommended) Sometimes manufacturers do not specify timing chain replacement intervals and design chains for engine life. However, once the recommended change interval has been reached, it is recommended to periodically check the condition of the chain and to change the chain if excessive stretching is detected or if unusual noises from the engine or other symptoms occur. |
