Engine reliability and common problems:
The B58 engine, compared to its predecessor, features a 20% increase in boost pressure, a closed-deck cylinder block design, an increased compression ratio of 11.0:1, and a slightly larger displacement of 2998 cc, up from 2979 cc, with an additional weight of 8 kg. Despite its advancements, the engine has several common issues.Coolant leaks are frequently reported, often linked to a drop in coolant levels without an obvious cause. In some cases, replacing the expansion tank cap resolves the issue. Head gasket failure is another recurring problem due to the engine's high operating temperatures. Symptoms include a strong smell of burning oil and sometimes visible smoke. Oil leaks are also common, originating from areas such as the oil filter housing, oil cooler, or head gasket. Prompt repairs are crucial to prevent oil starvation and potential engine damage.
The B58, like many direct-injection engines, often experiences carbon buildup on intake valves, leading to fluctuating idle and reduced performance. Less frequently, issues arise with the VANOS system, responsible for variable valve timing. Symptoms include power loss, uneven idle, stalling, and high fuel consumption. VANOS problems typically appear around 80,000–100,000 km. Oil filter disintegration is another concern, with parts of the filter sometimes breaking off and getting stuck in the housing. This can lead to oil leaks and other complications, often caused by low-quality filters or improper replacement.
Additionally, valve cover gaskets are prone to leaks, with symptoms such as the smell of burning oil, smoke, or low oil level warnings. Plastic valve covers can also crack over time. These issues usually arise between 60,000 and 100,000 km. Some BMW G-series models produced before 2021 may encounter failures in the oil pump due to a design flaw in the internal bushing. The recommended solution is upgrading to the sixth revision oil pump with a metal component.
Overall, while the B58 engine is a significant improvement in performance and efficiency, these known issues highlight the importance of regular maintenance, timely repairs, and the use of high-quality parts to ensure reliability.
Overall, this engine can last around 210,000 to 360,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
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.
