Expert Engine Rebuilds in Willenhall
Precision Engineering. Dealer-Level Expertise. Cost-Effective Solutions.
When your engine starts showing signs of serious wear—loss of power, strange noises, overheating, or poor fuel economy—don’t assume a full replacement is your only option. At The Car Doctor, we specialise in professional engine rebuilds that restore performance, reliability, and longevity without the cost of a new unit.
With over 15 years of experience working with BMW and Mercedes-Benz dealerships, our dealer-trained technicians bring unmatched expertise to every rebuild. We go beyond basic repairs—offering in-house diagnostics, component programming, and advanced mechanical restoration that many garages (and even some dealerships) simply can’t match.

What Is an Engine Rebuild?
An engine rebuild involves:
- Complete disassembly of your engine
- Thorough inspection of all internal components
- Replacement of worn or damaged parts
- Reassembly to factory specifications using OEM-grade parts and tools
This process restores your engine’s original performance, improves fuel efficiency, and extends its lifespan—making it a smart, sustainable alternative to full replacement.
