The BMW N63B44 engine is an 8-cylinder engine from the car manufacturer BMW, replacing the BMW M60 and M62 engine series, with technical characteristics that meet the high requirements of the modern automotive industry. Designed according to the concept of “Efficient Dynamics”, which means a combination of engine efficiency and driving comfort. In the quest to create an energy-intensive and environmentally friendly engine, BMW is making confident steps, although it is not so easy to do this.
This series can be safely called a new generation engine – direct fuel injection system, and, notably, two turbochargers located in the camber of the cylinder blocks are an innovation first developed by BMW engineers.

— official information
- Increased oil consumption. The problem is observed when the piston grooves coke and the rings begin to lose their function after the engine has traveled more than 50 thousand km. Major repairs required.
- Water hammer. The event occurs after a long idle engine. This is facilitated by piezo injectors, which have been constantly improved in the production cycle, but have not reached the ideal. It is necessary to replace the injectors with the latest released version.
- Ignition is lost. Breakage is associated with candles. It is necessary to replace them with copies from the M-sport-series.
Overconsumption of oil, often manifested by the lack of N63 motors, can be a consequence of the destruction of alusil. Replacement of the cylinder block will be required. Added to this is the close arrangement of pipes for supplying oil to the place of heat accumulation in the collapse of the block, as a result of which they quickly coke. The cooling and vacuum lines also suffer from excess heat in this place. Therefore, in order for the engine to work for a long time and without problems, you need to constantly monitor it and undergo maintenance.
