Diesel Engine Replacement
Diesel Engine Repair — Cheyenne, WY
Sometimes the honest answer is that the engine is done — spun bearings, a dropped valve, a cracked block, or wear that makes a rebuild cost more than it's worth. When that's the case, TDC handles complete diesel engine replacement: sourcing a quality replacement engine, transferring the components worth keeping, and doing the install with the care a five-figure job deserves.
The decision starts with a real assessment — compression testing and inspection — and a frank conversation about the numbers. A good used or reman engine in a solid truck is often far cheaper than a new truck payment, and Trevor will tell you straight if your truck is worth it or not.
What's Included
- Honest repair-vs-replace assessment first
- Quality used, reman or new replacement engines
- Careful transfer of accessories and components
- Break-in guidance and post-install follow-up
- Cummins, Powerstroke and Duramax platforms
Diesel Diagnosis Done Right
- Verify and inspect
Every diesel complaint starts with reproducing the symptom and a physical inspection — leaks, soot trails, boots, clamps and wiring.
- Test the systems
Compression tests, fuel system diagnostics and turbo checks isolate whether the problem is mechanical, fuel, or air.
- Confirm before replacing
Injectors, pumps and turbos are expensive. Nothing gets replaced until testing confirms it failed.
- Fix it for the long haul
Where a known weak point exists — like CP4 injection pumps or grid heater bolts — Trevor will tell you about the proven prevention options.
