Engine Overview and Common Failures

The weight of the K8-DE engine is 165 kg (including attachments). The engine number for the K8-DE is located at the junction of the block and the cylinder head. This fully aluminum engine is sensitive to overheating, so please keep an eye on the cooling system. Around 150,000 km, oil consumption may increase up to one liter per 1000 km. Furthermore, leaks from under the valve covers are often encountered during high mileage. The timing belt's lifespan is approximately 100,000 km, but it rarely causes valve bending if it breaks. Due to low-quality oil, hydraulic lifters might start making noise even before reaching 50,000 km.
