If your 6.7L Powerstroke, 6.6L Duramax, or Cummins engine is showing signs of wear or failure, don’t wait—let the experts at Divine Fleet & Auto Repair rebuild your engine and get your truck back on the road.
Why Choose Divine Fleet & Auto Repair for Your Diesel Engine Rebuild?
At Divine Fleet & Auto Repair, we offer professional diesel engine overhauls to restore performance, fuel efficiency, and longevity to your Powerstroke, Duramax, or Cummins engine. A well-executed engine overhaul can add hundreds of thousands of miles to your truck, making it an affordable and practical alternative to a complete engine replacement.
If your diesel truck is experiencing performance loss, oil leaks, excessive smoke, or frequent overheating, an engine overhaul may be the best solution to prevent costly breakdowns and major failures.
What is a Diesel Engine Overhaul?
An engine overhaul is a comprehensive service designed to restore an aging or high-mileage diesel engine by replacing worn internal components, reconditioning key parts, and ensuring the engine operates at peak efficiency.
Unlike a full engine rebuild, which requires complete disassembly and machining of major components, an overhaul focuses on internal restoration while keeping the engine block in place, making it a cost-effective way to refresh your engine.
Ideal for high-mileage trucks that need a performance boost
More affordable than a full engine rebuild
Less downtime compared to a full replacement
Extends the life of your engine by hundreds of thousands of miles
Our Diesel Engine Overhaul Process
At Divine Fleet & Auto Repair, we follow a detailed and precise overhaul process, ensuring your engine is restored to peak performance without unnecessary expenses.
1. Thorough Engine Inspection & Diagnostics
Before starting the overhaul, we conduct a full engine evaluation using:
-
Snap-on Zeus Scanners & Snap-on Pro Link – To diagnose fault codes, fuel delivery issues, and performance inefficiencies.
-
HP Tuners Platform – Used when data logging is required, allowing us to analyze fuel pressure, boost levels, and temperature fluctuations.
-
Compression Testing – Checks for low cylinder compression, which can indicate worn rings or valve issues.
-
Coolant & Oil Analysis – Determines if internal leaks, fuel contamination, or metal shavings are present.
2. Engine Disassembly & Component Inspection
During an overhaul, we partially disassemble the engine to inspect and replace key components that commonly wear out over time. This includes:
-
Removing and inspecting the cylinder head
-
Examining pistons, rings, bearings, and seals
-
Checking fuel injectors, glow plugs, and turbochargers
-
Inspecting timing components, camshaft, and lifters
Each part is assessed for wear and damage, and only the necessary components are replaced, making the overhaul more cost-effective than a full rebuild.
3. Cylinder Head & Valve System Refurbishment
The cylinder head plays a crucial role in engine efficiency, fuel economy, and power output. As part of the overhaul, we:
-
Remove and inspect the cylinder head for cracks or warping
-
Resurface the head to restore proper sealing surfaces
-
Replace valve seals, guides, and springs if needed
-
Clean and seat valves for proper combustion efficiency
A well-maintained cylinder head prevents compression loss, improves fuel combustion, and enhances overall engine performance.
4. Piston, Ring, & Bearing Replacement
Over time, piston rings and bearings wear down, leading to compression loss, oil burning, and reduced power. To restore performance, we:
-
Replace piston rings to restore proper cylinder compression
-
Install new main bearings and rod bearings to reduce friction and wear
-
Check piston-to-cylinder wall clearance to prevent excessive blow-by
By replacing these components, we eliminate excessive oil consumption and improve fuel efficiency.
5. Turbocharger & Fuel System Optimization
The fuel and turbocharging systems are critical to diesel engine performance and efficiency. As part of our overhaul, we:
-
Inspect and clean the turbocharger to ensure proper boost pressure.
-
Test and replace fuel injectors if needed to improve fuel atomization.
-
Service or replace the high-pressure fuel pump (HPFP) for proper fuel delivery.
-
Ensure proper function of glow plugs and intake air systems.
A well-maintained fuel and turbo system results in increased power, reduced emissions, and better fuel economy.
6. Cooling & Lubrication System Upgrades
-
Oil System Service – We replace the oil pump, oil cooler, and all gaskets and seals to ensure proper lubrication.
-
Cooling System Restoration – Includes water pump replacement, radiator flush, and thermostat inspection to prevent overheating.
-
New Fluids & Filters – We replace all fluids, oil, and fuel filters to protect your overhauled engine.
Proper cooling and lubrication extend engine life and prevent catastrophic failures.
Signs Your Diesel Engine Needs an Overhaul
A diesel engine overhaul is the best option when your truck exhibits these warning signs:
Loss of power & reduced fuel efficiency
High oil consumption or oil leaks
Coolant loss or frequent overheating
Excessive blow-by from the crankcase
Blue or white exhaust smoke
Tapping or knocking noises from the engine
Low compression across multiple cylinders
If you’re experiencing any of these issues, an overhaul can restore your engine’s performance without the cost of a full rebuild or replacement.
