This engine does not have any pronounced weak points; all its problems stem from aging. Most often, failures occur in the ignition system or some sensors malfunction. The timing belt has a relatively short lifespan, but if it breaks, the valves do not bend. If cheap oil is used, the hydraulic compensators may start knocking at around 100,000 km.
