About Our Comprehensive Diesel Engine Repair, Rebuild, Overhaul & Conversion Services
Not every diesel engine problem requires the same level of repair. Some failures can be corrected by replacing individual components, while excessive internal wear, compression loss, or recurring problems may call for a rebuild or complete overhaul. We evaluate the engine’s condition to determine the appropriate level of service for medium- and heavy-duty trucks.
- Heavy-Duty Diesel Engine Repair: Diagnosing and repairing injector problems, sensor faults, oil leaks, internal wear, and other issues affecting engine performance.
- Semi-Truck Engine Rebuilds: Replacing worn internal components to restore compression, oil control, power, and dependable engine operation.
- In-Frame Engine Overhauls: Servicing major internal components while the engine remains installed when its condition allows for an in-frame repair.
- Out-of-Frame Engine Overhauls: Removing and disassembling the engine when more extensive inspection, machining, or internal repairs are required.
- Cylinder Head and Head Gasket Repair: Addressing compression loss, sealing problems, coolant leaks, and damage involving the cylinder head or gasket.
- Diesel Engine Conversions and Repowers: Updating or adapting an engine configuration when replacement, application requirements, or alternative fuel needs make a conversion appropriate.
- Internal Engine Component Repair: Inspecting pistons, liners, bearings, rings, seals, and related components for wear that can contribute to low compression, oil consumption, or poor performance.
Our technicians use diagnostic testing and engine inspection results to determine whether targeted repairs, an in-frame rebuild, a complete overhaul, or another engine solution best fits the condition of the truck.
Maintain Reliable Engine Performance
A heavy-duty diesel engine must produce consistent power while operating under demanding loads and conditions. Repair, rebuilding, or overhauling worn engine components can restore performance and address problems affecting reliability. More extensive engine damage may require rebuilding or overhauling the engine rather than repairing a single component. An engine conversion can provide another option when the existing engine configuration no longer meets the truck’s needs.
Signs Your Truck Needs Engine Repair
Changes in power, engine operation, exhaust, or fluid consumption can indicate developing engine problems. A thorough inspection can determine whether the engine needs targeted repairs, a rebuild, an overhaul, or further evaluation for conversion.
- Loss of engine power: Diagnostic testing can identify worn or damaged components preventing the engine from producing consistent power.
- Excessive exhaust smoke: Inspecting engine operation can uncover combustion or internal component problems contributing to abnormal smoke.
- Knocking or unusual engine noise: Examining internal engine components can identify wear or damage responsible for abnormal operating noises.
- Excessive oil consumption: Checking for leaks and internal engine wear can determine why the engine is consuming more oil than expected.
- Low compression: Compression testing can identify internal wear that may require more extensive engine repair, rebuilding, or overhaul.
- Recurring engine problems: Evaluating the engine’s overall condition can determine whether continued individual repairs or a more comprehensive rebuild or overhaul is appropriate.
