Engine reliability and common problems:
The engine has a long service life if it is serviced on time and has reasonable fuel consumption. The most common problems are caused by the engine chain tensioner and the fuel delivery system.Overall, this engine can last around 220,000 to 370,000 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.
