What a Rebuild Actually Covers

Built From the Ground Up. Not Swapped Out.

A diesel engine rebuild at Chris’s Diesel Service is not a core swap. Every engine comes apart on our floor in Midland, TX. Every component is inspected, measured, and either restored to spec or replaced with OEM parts. Here is what that process covers.

Engine Teardown and Inspection
What We Do Full engine teardown with every component measured against manufacturer spec. Wear limits, clearances, and surface condition are documented before any parts are ordered. Nothing gets reused if it does not meet spec, and nothing gets replaced if it does.
Cylinder Head Repair and Resurfacing
What We Do Cracked cylinder head repair, valve seat and guide work, head surface measurement and resurfacing. A head that does not seal correctly is the most common cause of a comeback. We verify flatness and surface finish before the head goes back on.
Piston Replacement and Ring Fitting
What We Do Piston replacement with OEM or OEM-equivalent components sized to the bore. Ring end gaps are set to spec for the platform. For 6.4 Power Stroke piston replacement and similar high-wear applications, we use parts known to outlast the originals.
Crankshaft Repair and Main Bearing Service
What We Do Crankshaft inspection, journal measurement, and crankshaft repair where salvageable. Main and rod bearings replaced to OEM spec. If the crank is beyond repair, you get that conversation before the engine goes back together, not after.
6.7 Cummins and Power Stroke Overhaul
What We Do Platform-specific diesel engine overhaul procedures for 6.7 Cummins, 6.7 Power Stroke, 6.6 Duramax, and medium-duty diesel engines. Known failure points for each platform are addressed during the rebuild, not discovered afterward.
Assembly, Startup, and Road Test
What We Do Engine assembled to torque spec, break-in procedure followed, oil pressure and temperature verified at startup. Chris personally test-drives every rebuilt truck before release. Zero rebuilt engines returned for incomplete or incorrect work in 2025.
How It Works

Teardown. Measure. Rebuild It Right.

A diesel engine rebuild done right starts with an honest assessment of what the engine needs. We do not quote a rebuild before we know the scope, and we do not start work before you approve the numbers in writing.

  1. 01

    Teardown and Assessment

    Full engine teardown with every component measured and documented. Diesel engine rebuild cost is quoted based on actual wear measurements, not an estimate from the outside. You see exactly what needs replacing and why.

  2. 02

    Written Quote and Approval

    Itemized rebuild quote with OEM part numbers where applicable. If the engine is beyond cost-effective rebuild, we tell you that too. No work begins without your written approval on the full scope.

  3. 03

    Rebuild, Verify, and Release

    Engine rebuilt to manufacturer spec with OEM parts. Startup procedure followed, all pressures and temps verified, and personally test-driven by Chris before the truck leaves. Backed by our 3-year warranty.

Why In-House Matters

Not a Core Swap. A Real Rebuild.

Remanufactured diesel engines come with unknown histories and generic rebuild specs. An in-house diesel engine rebuild at Chris’s Diesel Service is built to your engine’s actual measurements, on our floor, by the same engine rebuild specialist who signs off every job.

  • No Exchange Units Your engine comes apart on our floor. You know exactly what went in, what was replaced, and why. Not a reman with an unknown history.
  • OEM Parts Throughout OEM parts when they exist, best available standard when they do not. Official Continental Battery and Bosch dealer. No gray-market internals.
  • All Platforms Power Stroke, Duramax, and Cummins diesel engine rebuilds including medium-duty and heavy duty platforms. Platform-specific procedures for every engine we rebuild.
  • 3-Year Warranty Every in-house diesel engine rebuild carries a 3-year warranty. We stand behind the work because we control every step of it.
Engine Rebuild FAQ

Common Questions

How much does a diesel engine rebuild cost in Midland, TX?
Diesel engine rebuild cost depends on the platform, the extent of wear, and which components need replacement. We quote every rebuild after teardown and measurement, not from the outside. You get an itemized number based on what your specific engine actually needs before any work begins. Call (432) 557-6500 to discuss your situation.
What is the difference between a rebuild and a remanufactured engine?
A remanufactured diesel engine is rebuilt off-site to a generic spec and sold as a core exchange. An in-house rebuild at Chris’s Diesel Service means your engine comes apart on our floor, every component is measured against your engine’s actual wear, and only what needs replacing gets replaced. You know exactly what went in and who built it.
Which diesel engines do you rebuild?
Power Stroke, Cummins, and Duramax diesel engine rebuilds for pickups, work trucks, and medium-duty applications. This includes 6.7 Cummins engine teardown and rebuild, 6.4 and 6.7 Power Stroke, and 6.6 Duramax. If you run a platform not listed, call and we will tell you straight whether it is in scope.
Does a rebuild include cylinder head and crankshaft work?
Yes. A full diesel engine rebuild covers cylinder head repair and resurfacing, crankshaft repair or replacement, piston replacement and ring fitting, main and rod bearings, gaskets, and seals. Every component is measured before the decision to repair or replace is made. Nothing is assumed.
What warranty comes with a diesel engine rebuild?
Every in-house diesel engine rebuild at Chris’s Diesel Service carries a 3-year warranty. In 2025 not a single rebuilt engine was returned for incomplete or incorrect work. If you need diesel engine repair short of a full rebuild, we handle that in the same shop to the same standard.
Do you rebuild diesel engines across the Permian Basin?
Yes. We serve Midland, Odessa, and the wider West Texas and Permian Basin region. For a full overview of our diesel services, see our diesel truck repair and engine rebuilds page.
