The truck in question is an impressive machine, equipped with a massive turbo and sleek aftermarket parts. However, it arrived at the shop with a serious issue—it wouldn’t start. The customer had initially reported excessive blue and white smoke, which is a clear sign of oil burning in the engine. When first inspected, the engine wouldn’t even run without starting fluid and struggled to operate on more than one cylinder.
Rebuilding the Heart of the Truck
To address the problem, the team decided to rebuild the engine, equipping it with premium components such as Speed of Air pistons, upgraded push rods, heavy-duty springs, and a Hamilton cam kit. The motor was thoroughly tested on a simulation machine, ensuring that compression and oil pressure were optimal before installation. This meticulous attention to detail is crucial in ensuring a reliable and high-performing engine.
For those who might require a replacement starter motor, a Cummins 4BT starter motor is an excellent choice. Ensuring compatibility and reliability when replacing components is critical for long-term performance.
Inspecting and Upgrading the Fuel System
As part of the rebuild, the team paid special attention to the fuel system. Contaminated fuel systems can cause injector failures, leading to severe engine damage. The team performed a complete system flush and installed SNS 30% over diesel injectors, ensuring that the engine would run efficiently. Additionally, the fuel filters were replaced, and the tank was sanitized to avoid future issues.
| Key Component | Upgrade |
|---|---|
| Injectors | SNS 30% Over Diesel Injectors |
| Pistons | Speed of Air Pistons |
| Fuel Pump | FASS System |
| Camshaft | Hamilton Cam Kit |

The Moment of Truth
After days of hard work, the engine was installed back into the truck. The team carefully bled the fuel system and filled it with oil, coolant, and power steering fluid. However, despite their meticulous preparation, the engine initially failed to start. Realizing that there might be air trapped in the fuel rail, they rechecked the pressure levels and ensured everything was in order.
Adjustments and Success
After addressing minor issues, the rebuilt engine finally roared to life. The team took the truck for a test drive, ensuring that it performed flawlessly under real-world conditions. With a fully upgraded engine and a clean fuel system, the truck was ready to hit the road, delivering top-notch performance and reliability for the owner.
