Why are 730d engine replacements 40% cheaper than 740i swaps?

The B57 diesel's modular design allows partial rebuilds (saving £3,800+), while N63 V8s in 740i models require full assembly replacement due to integrated turbos.

Cracked charge air coolers (under the supercharger)
Porosity in cylinder head channels
Plastic coolant pipe degradation

Specialist suppliers offer kits including:
Custom engine mounts for F01 chassis
Modified FlexRay wiring
EMF compatibility coding
