In modifications of this engine with a camshaft adjuster, it is the weak point. Sometimes it starts rattling as early as 60,000 km, and a new one is quite expensive.
The timing belt is scheduled to be replaced every 60,000 km, but in reality it lasts longer. Most often it breaks due to a seized water pump or tensioner pulley. The valves bend.
Owners of cars with this engine regularly encounter floating idle speeds. The cause may be contamination of the idle air control valve, throttle body, or injectors. Also often the culprit is air suction through cracks in the intake manifold.
This unit is equipped with a very archaic and weak oil pump, whose performance decreases with mileage and especially when saving on oil. By 250,000 km, the camshafts and their bearing journals often wear out, and it is easier to buy a new cylinder head.
All engines of this line are prone to oil or coolant leaks. The main weak points are the valve cover, front crankshaft seal, and oil separator. Coolant most often seeps through cracks in the thermostat housing.
The following components also have not the highest lifespan: engine mounts, crankshaft damper pulley, ignition coils, and crankshaft position sensor.
