For diesel owners, your timing chain is located on the back of the engine by the gearbox. This is why prices for these replacements are more expensive, due to increased labour costs. Unfortunately this visible check method isn’t possible for these N47, N57, B37, B47, B57 engines.Common BMW Timing Chain Problems BMW engines are known for performance, but some models — particularly N47, N57, and early B47 diesels — are notorious for timing chain wear or failure. Typical issues include: Chain stretch – over time, the chain elongates, throwing engine timing off.Given the B47 vs N47 comparison, the B47 tends to offer better long-term reliability, particularly if proper maintenance is performed.

Is a twin turbo a good engine?
Twin-turbos allow smaller engines to produce horsepower and torque equal to that of larger, less efficient engines—yielding better fuel economy, lower emissions, and in many cases, more consistent performance. They are costly to make and complex to install, requiring a lot of pipes. Lastly, series twin turbos are used in piston-engine aircraft and high-performance diesel engines. Their applications are limited because they are used to generate larger boost levels at lower RPM.There are pros and cons to each setup. Single turbo systems are typically more efficient because the exhaust gases travel along a simpler, more direct route. Twin-turbo systems can make more power because they produce more boost. However, they are typically more complex.
