Strengths
Provides hurricane-like dynamics
Great tuning potential
Watch-outs
Quite high fuel consumption
Early versions have many problems
Very picky about fuel and oil
Known engine issues
Early year problemsThe first engine modifications caused a lot of trouble: rapid wear of bearings, peeling coating in cylinders, short life of timing chains, and even bursting spark plugs. However, it should be noted that all defective components were replaced under warranty without issue.
Oil consumptionThe majority of owner complaints on specialized forums are related to oil consumption. The culprits are usually stuck piston rings or hardened valve stem seals, but sometimes the cause can be a faulty crankcase ventilation system.
Coolant leaksIn some operating modes, this engine forces coolant out of the reservoir and it leaks directly onto the coils and injectors, which usually leads to serious breakdowns. Therefore, purchasing a plastic deflector to divert antifreeze is highly recommended.
Listed from most frequently reported, each with its source.
Throttle body/injectors and rough running
Often reported
In some examples, the electromechanical throttle body can stick and cause limp mode, especially around 50-80,000 km; injectors are also reported to cause rough running or engine vibration.
Engine Bay
Faulty CCV/PCV and carbon buildup
Often reported
The crankcase ventilation system (CCV/PCV) on the N63 engine can clog or fail, causing oil vapors to leak into the intake manifold and contribute to carbon buildup on valves due to direct injection.
Engine Internal
Timing chain and guide wear
Often reported
The timing chain and plastic guides on the N63 engine are prone to wear; this can lead to chain stretch, noise, rough running, and in extreme cases, timing slip causing severe engine damage.
Timing chain
Turbo failures due to oil blockage
Often reported
Turbos can be damaged by oil residue buildup (coking) and blocked oil passages, especially if the engine is consuming or leaking oil.
