Engine reliability and common problems:

This engine stands out for its durability and generally remains trouble-free until it has been used extensively over many years. Despite its robust construction, the wear and tear from prolonged use, particularly in aging and low-cost vehicles, has started to reveal weaknesses. One of the most serious issues is the failure of the timing belt, which requires replacement every 60,000 km to prevent catastrophic engine damage. Common faults also include burnt valve seats, which result in a loss of compression, and oil leaks that are frequently traced to a broken lower flange in the crankcase ventilation system. Engine performance problems are often linked to malfunctions in the turbo management system, airflow meter, or EGR valve. Another critical concern arises when fragments of the serpentine belt, often caused by a damaged roller, interfere with the timing mechanism, leading to severe engine failure. The mechanical injectors feature a control injector equipped with a timing sensor, and if this sensor fails, the engine shifts into a limp mode, drastically reducing power output beyond 2000 rpm, with diagnostics identifying a loss of communication with the needle lift sensor.
Overall, this engine can last around 400,000 to 670,000 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.

Number of cylinders	4
Bore (cylinder diameter)	79.5 mm
Stroke length (piston move)	95.5 mm
Compression ratio	19.5 : 1
Camshaft drive	Timing belt Timing belt engines are generally quieter and less vibrating than chain engines, but belt usually needs to be replaced more often and the risk of breakage is higher. More service info
Timing belt change interval	60,000 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.
