The BMW M5, particularly the F10 model with its twin-turbo V-8 engine, is notorious for reliability issues as mileage increases. A recent teardown video by the I Do Cars YouTube channel showcases one such problem that led to a motor failure in this high-performance vehicle.
The 4.4-liter V-8 engine, codenamed S63TU, was dismantled to uncover the cause of its sudden highway failure. Despite the complexity of the disassembly, initial inspections of the turbochargers, camshafts, and cylinder walls showed no obvious damage. However, the oil pan revealed metal flakes and larger chunks, indicating internal damage.
The root cause was discovered when the main caps were removed, exposing a spun and fused crankshaft bearing. Additionally, heavily worn rod bearings were found, suggesting significant wear even though the BMW F10 engine had only 103,000 miles.
BMW M5 F-10 owners are advised to proactively replace bearings to avoid similar catastrophic failures, potentially saving significant repair costs.
