Engine reliability and common problems:
This engine features a thin-walled cast-iron cylinder block, an aluminum cylinder head with dual overhead camshafts, a timing belt system, two balance shafts, hydraulic lifters, a dual-mass flywheel, and a dampened crankshaft pulley. It has received numerous positive reviews from car owners due to its reliability and long lifespan, which can reach up to 500,000 km. It is also well-suited to average fuel quality, has no issues with servicing or spare parts availability.Despite its advantages, the engine has some weaknesses. Engine mounts typically require replacement after 200,000 km. Worn mounts can cause vibrations in the steering wheel, jolts when shifting gears, and a misalignment of the engine. Oil leaks are a common issue, especially from the oil pressure sensor located under the exhaust manifold. This can lead to significant oil consumption.
The throttle body, with its cable-operated mechanism, requires periodic cleaning of the idle regulator due to soot buildup. Valve burnout is another potential problem, often caused by worn guide bushings and excessive carbon buildup on the valve face, leading to localized overheating and reduced compression.
The engine's timing belt drives both camshafts and the water pump. The belt, along with the tensioner, water pump, auxiliary roller, and crankshaft and camshaft seals, should be replaced every 100,000 km. Conveniently, all timing marks are clearly indicated on the pulley, simplifying the replacement process.
Other noted issues include head gasket failures, which can result in oil leaks, and recurring electrical problems. While the engine offers impressive durability, these common maintenance tasks and known issues should be addressed to ensure long-term performance and reliability.
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 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. However, the timing belt change interval for a particular engine is long enough to be comparable to the life of some engine chains. More service info |
