Engine Diagnostics & Overhauls

We scan every major heavy-duty platform, read the codes, and verify the failure before pulling a wrench. Repairs run from sensor swaps to complete in-frame and out-of-frame overhauls.

The Work

How we do it.

A check-engine light is a clue, not a diagnosis. We pull live data, pressure test where it matters, and confirm the root cause before quoting parts.

On the heavy work, in-frames, out-of-frames, head jobs, we use OEM torque specs, new gaskets and studs, and document every step so the engine goes back together stronger than stock.

What's Included
  • Live data scans on Cummins, CAT, Detroit, PACCAR, Volvo
  • In-frame and out-of-frame overhauls
  • Injector, turbo, EGR, and aftertreatment work
  • Oil and coolant analysis when something doesn't add up
  • Test runs and post-repair scans before hand-over
