Tell Us the Symptom. We Find the Cause.

You do not need to arrive with a diagnosis. Describe what the truck is doing and we take it from there. These are the diesel engine complaints we hear most in Midland, Odessa, and across West Texas, and the path each one usually takes.

Hard starts, especially cold mornings
Likely Path Glow plugs or intake heater, fuel pressure bleeding down overnight, or weak batteries dragging cranking speed. We test each in order instead of replacing injectors on a battery problem. The cheap cause gets ruled out before the expensive one gets quoted.
White smoke at idle or on startup
Likely Path Unburned fuel from injector timing or low compression, or coolant entering a cylinder from a head gasket or EGR cooler. A compression test and cooling system pressure test separate the two quickly. Coolant in a cylinder is a same-week problem, and we will tell you so.
Black smoke and poor fuel economy
Likely Path Overfueling or restricted air: injectors stuck rich, boost leaks, a tired turbo, or a clogged air filter. We road-test with live data to watch fueling and boost under load, then quote the specific failure instead of throwing parts at the smoke.
Knocking or a new noise under load
Likely Path Injector knock, a failing lifter or rocker, exhaust leak rattle, or in the worst case a rod or main bearing. We isolate the noise by cylinder and condition before anything comes apart. If it is bottom-end, you get the honest rebuild conversation, not a band-aid.
Coolant disappearing with no puddle
Likely Path Pressure-test first. If the system holds, suspicion moves to the EGR cooler or a head gasket pushing coolant into the cylinders. Caught early this is a repair. Driven on for months, it becomes an engine. Bring it in the week you notice it.
Oil pressure low or oil level rising
Likely Path Low pressure points to bearings, the oil pump, or a pressure sensor lying to you. A rising level means fuel dilution from a leaking injector or incomplete regens. Both get verified with real gauges and a sample before any teardown is quoted.

Diagnose. Quote. Repair It Once.

Diesel engine repair service goes wrong when shops skip the first step. We do not start a repair until we can tell you what failed, why it failed, and what it costs to fix correctly.

  1. 01

    Pinpoint the Failure

    Live data, compression and leak-down testing, fuel pressure checks, and a road test under load. The diesel engine inspection names a component and a cause, not a guess and a parts list.

  2. 02

    Quote in Writing

    Itemized quote before any work begins, with the why behind each line. If something can safely wait, we say so. If the engine is past repair, you get the rebuild conversation honestly.

  3. 03

    Repair & Verify

    Manufacturer-grade diesel engine repair service with OEM parts. Verified with the same tests that found the problem, then personally test-driven by Chris before the truck goes back to work.

No Parts Cannon. No Repeat Failures.

The most expensive diesel engine repair is the one that did not fix the problem. Precision diesel engine diagnostics exist to prevent repeat failures, and the repair standard exists to make the first fix the last one.

  • Test Before Teardown Compression, leak-down, fuel pressure, and live data under load before anything is disassembled. The quote is built on evidence.
  • OEM Standard OEM parts when they exist, best available standard when they do not. Official Continental Battery and Bosch dealer. No gray-market internals in your engine.
  • All Platforms Power Stroke, Duramax, and Cummins pickups, medium-duty trucks, and heavy duty diesel engine repair including semis. In the trade since age 12, and it shows on the hard diagnoses.
  • Test-Driven by Chris Every diesel engine repair is verified and personally test-driven before release. Zero vehicles returned for incomplete or incorrect repairs in 2025.

Common Questions

How do you diagnose a diesel engine problem?
We start with live data and a road test to see what the engine does under real load, then verify with physical tests: compression, leak-down, fuel pressure, and cooling system pressure. The diesel engine inspection names the failed component and the reason it failed, so the repair addresses the cause and not just the symptom.
Which diesel engines do you work on?
Power Stroke, Duramax, and Cummins pickups, medium-duty work trucks, and heavy duty diesel engine repair including semis. Gas, propane, and natural gas engines are also serviced in the same shop. If you run something unusual, call and we will tell you straight whether it is in scope.
Should I keep driving with white smoke or coolant loss?
No. White smoke with coolant loss often means coolant is entering a cylinder through a head gasket or EGR cooler. Caught early it is a repair. Driven on for weeks, it can wash cylinder walls and damage bearings until the engine needs a full diesel engine rebuild. Bring it in the week you notice it.
What if my engine is too far gone to repair?
Then we tell you that before you spend repair money on it. Chris performs diesel engine rebuilds in-house, never outsourced, and every rebuild carries a 3-year warranty. You get a written comparison of repair versus rebuild with honest numbers so you can make the call with real information.
What does diesel engine repair cost in Midland, TX?
It depends entirely on the failure, so every job is quoted custom after diagnosis and in writing before work begins. We flag what is urgent and what can safely wait, and we will not sell you work the engine does not need. Call (432) 557-6500 and tell us what the truck is doing.
Do you service 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 everything we handle, see our diesel truck repair and engine rebuilds page.

Engine Acting Up?

Bring it in before a symptom becomes a teardown. We will diagnose the actual cause, quote it in writing, and fix it once.
