Diesel Piston Replacement
Diesel Engine Repair — Cheyenne, WY
A melted or cracked piston — usually the result of an injector washing a cylinder, extreme heat from hard tuning, or a foreign object — takes one cylinder down and puts metal where it shouldn't be. Compression testing and inspection confirm which cylinder failed and, just as important, why it failed.
TDC performs piston and bottom-end repairs with attention to the root cause: the injector, tune, or airflow problem that killed the piston gets addressed too, or the new piston meets the same fate. On performance builds, upgraded pistons and machine work are part of the conversation.
What's Included
- Failed cylinder confirmed by compression testing
- Root-cause diagnosis — injectors, tuning, airflow
- Quality pistons, rings and bearings
- Machine work coordinated when needed
- Stock rebuilds and performance builds
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.
