The assembled weight of the LL8 engine is 215 kg. The LL8 engine number is located at the junction of the block and the gearbox. The engines of the very first year of production were subject to recall due to cylinder liner sagging. Overall, it is a fairly reliable unit, but not everyone will be pleased with its fuel consumption. After 200,000 km, you may encounter valve seat wear and chain elongation. The fan viscous coupling has a relatively short service life, and the engine is prone to overheating. The exhaust manifold is also considered a weak point, as it often cracks.
