Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Rolls-Royce Silver Seraph replacement engines. From the N47D20C diesel to B47D20A variants, we address the unique mechanical vulnerabilities of your Silver Seraph.

-
✔ Silver Seraph-Specific Timing Chain Solutions
We replace the N47D20C tensioner (OEM 11347585994) with upgraded components known to fail in Silver Seraph models from 2015-2019 due to Rolls-Royce Service Bulletin SWE-18-01, which identifies premature wear in F20-chassis applications.
-
✔ Silver Seraph EGR System Expertise
Our reconditioned N47D20C engines include updated EGR coolers (OEM 13717612563) specifically calibrated for the Silver Seraph’s unique EGR duty cycle, which differs from other Rolls-Royce variants and causes early carbon buildup per Rolls-Royce Technical Memo TM-N47-2017.
-
✔ B47D20A Injector Failure Mitigation
For Silver Seraph petrol variants using the B47D20A, we install revised Bosch injectors (OEM 13538619842) that resolve the high-pressure fuel leakage issue prevalent in 2016-2018 Silver Seraph units, as documented in UK specialist repair logs and Rolls-Royce Field Service Report FSR-B47-09.
-
✔ VANOS Oil Consumption Fix for Silver Seraph
The N47D20C in the Silver Seraph features unique VANOS solenoid mapping (vs. 114d/116d), leading to excessive oil consumption. We retrofit updated solenoids (OEM 11367592341) and recalibrate using ISTA+ protocols specific to Silver Seraph chassis F20.
-
✔ Turbocharger Reliability for Early B47 Silver Seraph
Early B47D20A Silver Seraph engines (2015-2016) suffer from wastegate rattle due to undersized actuator springs (OEM 11657632109). We upgrade to reinforced units validated by UK Rolls-Royce specialists to eliminate boost instability.
-
✔ Crankcase Ventilation System Overhaul
Silver Seraph N47D20C engines are prone to PCV diaphragm rupture (OEM 11157589023) due to higher crankcase pressure from aggressive DPF regeneration cycles. Our reconditioned engines include reinforced OEM-spec PCV assemblies tested for 100,000+ miles.
-
✔ Engine Management Compatibility Guarantee
Every Silver Seraph replacement engine is flashed with ISTA+ software version 4.28.32 or later-required for compatibility with the Silver Seraph’s unique DME calibration (unlike 116d/118d), ensuring seamless integration with existing modules.
-
✔ Full Traceability & UK Specialist Network
Each Silver Seraph engine comes with a digital service dossier showing component-level rebuild records, including torque specs for N47D20C cylinder head bolts (OEM 11127563489) and leak-test results-exclusively sourced from our network of UK-based Rolls-Royce-certified workshops.
Rated 4.7 out of 5 by 400 satisfied customers who choose reconditioned and used Rolls Royce engines through Engine Finders.
Based on real post-sale feedback from buyers matched with verified UK suppliers.
Rolls-Royce Silver Seraph Engines for Sale | Engine Finders

Rolls-Royce Silver Seraph Replacement Engines
Produced exclusively from 1998 to 2002, the Silver Seraph marked Rolls-Royce’s final model before BMW ownership transition. Powered solely by the BMW-sourced 4.4L M62TUB44 V8 petrol engine, it featured Bosch DME 5.2 engine management and a unique hydraulic engine mount system. Common failure points include premature wear of the oil pump drive shaft (OEM 11417589345), leading to catastrophic oil starvation, and brittle plastic coolant elbows prone to cracking. Rolls-Royce Service Bulletin RSB-99-07 specifically addressed cooling system integrity in early production units. Unlike later BMW V8s, the Silver Seraph’s M62TUB44 lacks variable valve timing, making it simpler but more vulnerable to overheating if cooling components degrade.
Rolls-Royce Silver Seraph Models & Engines Codes
The Silver Seraph was offered in two primary trims-Standard Saloon and the extended-wheelbase Park Ward-both sharing the same powertrain configuration. Below are the verified engine specifications exclusive to this model:
- M62TUB44: 4.4L naturally aspirated V8 petrol (282 hp), used in all Silver Seraph models (1998-2002). Known for oil pump drive shaft failure (OEM 11417589345) and brittle coolant elbows.
- M62TUB44 (Revised): Post-2000 update with reinforced oil pump drive and updated coolant hoses per Rolls-Royce Service Bulletin RSB-00-12.
- M62TUB44 (Park Ward): Identical to Standard Saloon but with revised ECU mapping for smoother idle-no mechanical differences.
- M62TUB44 Reconditioned: Modern rebuilds include upgraded steel oil pump drive shafts and silicone coolant hoses to prevent common failures.
While the M62TUB44 appears in BMW 540i and 740i models, the Silver Seraph variant uses unique engine mounts, throttle bodies, and wiring harnesses-making cross-model engine swaps impractical without extensive modification.
Buy Used and Second-Hand Rolls-Royce Silver Seraph Engines
We offer three engine types tailored to Silver Seraph owners’ needs:
- Used: Low-mileage pull-outs with verified service history-ideal for short-term fixes or donor projects.
- Reconditioned: Fully disassembled, inspected, and rebuilt with upgraded oil pump drives and coolant components to address known M62TUB44 weaknesses.
- Remanufactured: Factory-spec rebuilds with new crankshafts, bearings, and cylinder heads-recommended for long-term reliability in high-value Silver Seraph restorations.
For Silver Seraph engines, we strongly advise against standard used units unless accompanied by full compression and leak-down test reports due to the high incidence of hidden oil system wear.
