Four Steps. No Shortcuts.

Every engine repair and rebuild at Chris’s Diesel Service follows the same four steps. Diagnose correctly. Quote honestly. Build carefully. Verify before delivery.

  1. 01

    Diagnose and Inspect

    We perform a full vehicle diagnostic and physical inspection to find the failure and decide whether the engine needs a targeted repair or a complete rebuild.

  2. 02

    Written Quote First

    You get an itemized parts and labor quote with OEM versus alternate parts clearly explained before any work begins. No surprises on the invoice.

  3. 03

    Repair or Rebuild

    All engine repair and rebuild work is completed in-house at our Midland shop. Machine work is coordinated locally and every major step is documented as the job progresses.

  4. 04

    Test and Verify

    Every engine goes through startup checks, timing verification, cooling system testing, and a real road test before the vehicle is released.

The Standard Behind Every Engine Repair

A good engine rebuild comes down to three things: the right parts, accurate work, and proper testing before the vehicle leaves. Every engine repair and rebuild at our Midland shop follows the same standard.

  • OEM First We use OEM engine components where they exist and trusted alternatives where OEM parts are no longer available.
  • Built

Common Questions

Do you repair gas and diesel engines?
Yes. We repair gas and diesel engines for passenger vehicles, pickups, and work trucks. For heavy-duty diesel trucks and semi engines, see our diesel engine repair service.
When should an engine be rebuilt instead of replaced?
If the engine block and major components are still good, a rebuild is usually a better long-term option than a full replacement. We look at the condition after teardown and tell you honestly which path makes sense.
How long does an engine rebuild take?
It depends on the engine condition, machine shop turnaround, and parts availability. We give you a written timeline before work starts and keep you updated as the job progresses.
Do you use OEM parts?
Yes. OEM engine components whenever available and quality replacement parts when OEM parts are discontinued. We explain exactly what is going into your engine before work begins.
Can you repair engines another shop already worked on?
Yes. We inspect the previous work, document what is there, and quote only what actually needs to be done. We will not redo good work or sell you parts you already have.
