Professional 5.8L Windsor Engine Remanufacturing Process
A quality Ford 5.8L remanufactured engine starts with a complete
teardown rather than simply replacing a few worn components. Each engine goes through
multiple stages of cleaning, inspection, machining, assembly and testing.
1. Deep Cleaning
The engine is completely disassembled before cleaning. Cast-iron components are
hot tanked, while aluminum components are thermally cleaned where applicable.
This process removes accumulated oil, carbon, dirt and other contaminants so that
components can be properly inspected.
2. Detailed Inspection
Engine components are visually inspected for wear, damage and other conditions that
could affect performance. Magnaflux testing is used on appropriate metal components
to help identify microscopic cracks and fissures that may otherwise be difficult to detect.
3. Precision Machining and New Components
Required machining operations are performed to restore critical surfaces and
dimensions. Deck surfaces are CNC machined, while worn or required components are
replaced during assembly.
Depending on application and component condition, new components may include
bearings, pistons, piston rings, lifters, oil pump, gaskets, Viton valve seals,
freeze plugs, galley plugs and timing components.
4. Final Assembly and SIM Testing
After assembly, each engine is SIM tested. The cooling and oil systems are pressurized,
while the crankshaft is spun at high RPM to help verify compression, oil pressure,
cooling-system pressure and overall build quality.

machining, assembly and testing process rather than a simple component replacement.
