Overall, this engine can last around 270,000 to 450,000 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.

Camshaft drive Timing chain

Chain motors are considered more reliable, chain replacement usually is required less often than a timing belt, but they are often louder and vibrate more.

More service info
Timing chain change interval 250,000 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.

Fuel system Common Rail

Common rail fuel injection provides more engine power, is quieter, more environmentally friendly and offers better fuel economy, but is more expensive to maintain and repair.
