We work on the major engine platforms found in today's trucks and explain every recommended repair in plain language. The goal is simple: restore power, reliability, and fuel efficiency without replacing parts you don't need.

What We Offer

Repairs and Maintenance That Keep Your Engine Pulling Strong

Most engine failures start with small warning signs like rough idling, extra smoke, or a slight drop in fuel mileage. We handle everything from routine maintenance that prevents those problems to repairs that fix them fast. Here's what our diesel engine service includes:

Diesel Engine Repair and Maintenance By I-55 Truck and Trailer Repair
  • Engine Diagnostics: We scan the engine's computer and run hands-on tests to identify the root cause of performance issues. Accurate diagnosis saves you time and prevents unnecessary repairs.

  • Loss of Power Repair: Low power can come from fuel, air, exhaust, or sensor problems. We track down the cause and restore the pulling power your truck needs under load.

  • Fuel Injector Service: Worn or leaking injectors waste fuel, cause smoke, and can damage the engine over time. We test, clean, and replace injectors to restore smooth, efficient combustion.

  • Turbocharger Repair: A failing turbo can cause whistling, smoke, and a big drop in performance. We inspect, repair, or replace turbochargers and check the related air intake components.

  • Oil Leak and Gasket Repair: Leaking seals and gaskets can lead to low oil levels and engine damage. We locate the source and replace worn gaskets to stop the leak for good.

  • Valve Adjustments and Overhead Service: Proper valve lash keeps your engine running smoothly and efficiently. We adjust valves and service overhead components according to manufacturer intervals.

  • EGR System Repair: Clogged EGR valves and coolers can cause rough running, soot buildup, and warning lights. We clean or replace EGR components to keep your engine and aftertreatment healthy.

  • Preventive Engine Maintenance: Regular oil changes, filter replacements, and inspections are the best protection for your engine. We keep your truck on a maintenance schedule that helps it reach its full lifespan.

Frequently Asked Questions

What are the warning signs of diesel engine trouble?

Watch for loss of power, excessive smoke, hard starting, rough idling, unusual knocking, rising oil consumption, and a check engine light. Any of these is a good reason to have the engine inspected.

What does black, white, or blue exhaust smoke mean?

Black smoke usually points to a fuel or air intake problem, white smoke can mean coolant or unburned fuel, and blue smoke often signals oil burning. Each needs a proper diagnosis to confirm the cause.

Do you work on all diesel engine brands?

We service the major diesel engine platforms used in commercial trucks. Call (870) 635-4003 with your engine make and model, and we'll confirm we can help.

When does an engine need a rebuild instead of a repair?

If the engine has major internal damage, low compression, or excessive wear across multiple components, a rebuild may be more cost-effective than ongoing repairs. We'll walk you through both options after diagnosis.

How often should a diesel truck engine be serviced?

Service intervals depend on the engine, oil type, and how the truck is used. We follow manufacturer recommendations and can set up a custom schedule for your truck or fleet.
