Character
N62
"Valve stem seal failure (30%+ by 160k km). Coolant transfer pipe leak = 40+ hours labour. Timing chain guide brittleness. Over-engineered with too many failure points. Beautiful power, terrible ownership."
M50
"Cast iron block legend. One of BMW's most reliable ever. M50TU added single VANOS. Strong internals handle 300k+ km. Cooling plastics only weakness."
