How is an Engine Rebuild Performed?


You love your car, but your car's engine has seen better days? So what do you do? You have a few viable options that include replacing your engine or replacing your whole car, which probably isn't a very favorable choice. Another possibility would be to have your engine remanufactured by a professional auto mechanic. Once a remanufactured engine is complete it is basically a brand new engine that should last for hundreds of thousands of miles with proper maintenance. So how is an engine remanufactured?

1. Removal, Cleaning and Inspection

The first step in remanufacturing an engine is to completely remove all engine components from under the vehicle's hood, disassemble the engine and cleaned. The cleaning process can be done in several ways, depending on the parts, such as steam cleaning for cylinder heads and oil pans. After everything has been cleaned to the bare metal the parts are inspected for wear and measured to be prepped for machining in order to return them to their factory specifications, or better!

2. Machining

Parts are machined to return their smooth surfaces and allow parts to run smoothly again. The engine block is bored and honed, the crankshaft is ground and bearing surfaces and chamfer oil passages are micropolished. Connecting rods are straightened and mated to rods. Cylinder heads are resurfaced and valve seals are recut. All other parts are machined to proper surface and spec.

3. Engine Reassembled

During reassembly new free plugs and oil galley plugs are installed. New main and rod bearings and a new timing belt and gears are installed. All new seals and gaskets are used throughout the engine.

4. Testing

The engine is tested for proper compression and oiling. Any adjustments are made and any leaks repaired.

5. Reinstallation

After all parts are completely rebuilt, machined and tested the engine is ready to be reinstalled and final testing is performed.

The remanufacturing process is very intricate and much testing and detail goes into every step to ensure the final product results in a like-new engine.
