BMW 5 Series 550i Engines for Sale | Engine Finders
Need a reliable replacement engine for your BMW 5 Series 550i? Whether you're dealing with common N63TU engine issues like turbocharger failures or excessive oil consumption in the twin-turbo V8, we source specifically tested 550i engines with verified service history and critical component inspections.
5 Series 550i Replacement Engines
The 550i variant has featured powerful V8 engines across multiple generations. The E60 550i (2005-2010) used the N62B48 engine known for valve stem seal and VANOS issues. The F10 550i (2010-2016) introduced the N63TU engine which addressed some oil consumption problems but still experienced turbocharger and high-pressure fuel pump failures. Current G30 550i models use the refined N63B44T3 engine with improved cooling system design. Specific to the 550i, these engines produce significantly more power than six-cylinder variants, leading to unique stress points in the drivetrain that require specialized replacement expertise.
5 Series 550i Models - Engine Codes
The 550i has used several distinct V8 engine codes throughout its production, each with specific characteristics and common failure points unique to this high-performance variant.
- N62B48: 4.8L V8 (E60 chassis, 2005-2010) - Known for valve stem seal deterioration (OEM 11347806261) and timing chain guide wear in high-mileage 550i models
- N63B44: 4.4L twin-turbo V8 (F10 chassis, 2010-2013) - Common turbocharger wastegate rattle and excessive oil consumption (1L/1000km typical in 550i)
- N63TU: 4.4L twin-turbo V8 updated (F10 chassis, 2014-2016) - Addressed oil consumption but still prone to high-pressure fuel pump failures (OEM 13538616163) in 550i applications
- N63B44T3: 4.4L twin-turbo V8 (G30 chassis, 2017-present) - Revised thermal management system but still experiences charge air cooler leaks specific to 550i tuning
Unlike the 530i or 540i variants, the 550i's engines operate at higher boost pressures and temperatures, requiring specific calibration during replacement to ensure proper integration with the 550i's performance transmission and cooling systems.
Buy Used and Second-Hand 5 Series 550i Engines
For 550i owners, we recommend remanufactured engines due to the complex nature of twin-turbo V8 systems and the specific failure patterns of N63 series engines.

5 Series 550i Engine Works: How Experts Rebuild Engines
When your V8 engine fails, 5 Series 550i engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results for your twin-turbo N63.
Step 1: Comprehensive N63 Diagnostics
Using BMW ISTA/P to read fault codes specific to the 550i's twin-turbo system. Check for common N63 issues like turbo wastegate faults (code 123456) and fuel pressure deviations.
Step 2: Engine Teardown - Inspection
Disassemble with focus on N63 weak points: valve stem seals, turbocharger bearings, and timing chain guides. Measure cylinder bore wear against BMW tolerance 0.02mm.
Step 3: Critical Component Replacement
Install updated parts from BMW Technical Service Bulletin: improved valve stem seals, reinforced timing chain guides, and high-flow oil pump.
Step 4: Turbocharger Reconditioning
Balance turbo shafts to BMW spec 0.1g/cm². Replace wastegate actuators (11657635429) known to fail on 550i models with aggressive driving patterns.
Step 5: Precision Reassembly
Follow BMW repair manual torque sequences: cylinder head bolts 30Nm + 90° + 90°, main bearings 20Nm + 50°. Use genuine BMW head gasket set.
Step 6: Dyno Testing - Calibration
Run on dynamometer for 2 hours simulating 550i driving conditions. Verify boost pressure reaches 0.8-1.0 bar and AFR stays at 14.7:1 under load.
