Engine Rebuild

Diesel engines can often be repaired without full disassembly. However, certain conditions indicate that a rebuild may be required.

Common signs include:

• Low engine compression
• Excessive oil consumption
• Severe overheating damage
• Persistent knocking or internal noise
• Blown head gasket
• Cracked cylinder head
• Major turbo-related internal damage
• Metal contamination in oil
• Catastrophic component failure

If internal engine components such as pistons, rings, bearings, crankshafts, or cylinder heads are worn or damaged, rebuilding may restore proper performance and extend engine lifespan.

Before recommending a rebuild, we perform comprehensive diagnostics and engine evaluation.

Our rebuild process begins with:

• Compression testing
• Cylinder leak-down testing
• Oil system analysis
• Cooling system evaluation
• Fuel system inspection
• Electronic diagnostics

If internal wear is confirmed, the engine is carefully removed and disassembled. Each component is inspected for wear, scoring, cracking, or structural damage.

A proper diesel engine rebuild requires precise measurement of critical components.

We evaluate:

• Cylinder wall condition
• Piston wear
• Ring integrity
• Crankshaft journals
• Connecting rods
• Main and rod bearings
• Camshaft components
• Cylinder head surfaces

Worn or damaged components are replaced or reconditioned according to manufacturer specifications.

Cylinder heads play a crucial role in diesel engine compression and combustion efficiency. Warped or cracked heads can lead to compression loss, overheating, or coolant contamination.

We inspect and service:

• Cylinder head surfaces
• Valve seats and valves
• Head gasket surfaces
• Injector ports
• Glow plug ports

Proper resurfacing and gasket replacement ensure optimal sealing and long-term reliability.

When performing a diesel engine rebuild, it is essential to evaluate related systems that may have contributed to engine damage.

We inspect:

• Fuel injectors
• High-pressure fuel pumps
• Turbochargers
• Intercoolers
• Air intake systems

Addressing these components during the rebuild process helps prevent repeat failures and ensures full engine performance.

We rebuild major diesel platforms including:

• Ram Cummins engines
• Ford Power Stroke engines
• Chevrolet and GMC Duramax engines

Each engine platform has unique tolerances, internal design differences, and known wear patterns. Our technicians understand manufacturer-specific rebuild procedures and apply correct torque specifications and component standards.

A professionally rebuilt diesel engine offers several advantages:

• Restored compression and performance
• Improved fuel efficiency
• Extended engine lifespan
• Improved reliability for towing and hauling
• Cost savings compared to full engine replacement

For many truck owners in Boise and the Treasure Valley, rebuilding provides a dependable alternative to purchasing a new vehicle.

In some cases, engine replacement may be considered. However, rebuilding allows:

• Retention of original engine block
• Custom inspection of internal components
• Replacement of worn parts with updated components
• Controlled quality during reassembly

Our team helps you evaluate the most appropriate solution based on engine condition and long-term goals.
