Short Block Engine

Remanufacturing Process

Remanufacturing is a very thorough factory process where the engine is completely disassembled, thoroughly cleaned, carefully inspected, and conditioned and machined to original equipment manufacturer (OEM) tolerance specifications. The finished engine is then tested using state-of-the-art computerized equipment. Remanufacturing is similar to building a new engine whereas rebuilding will not result in the same high quality product.



How Remanufacturing Is Done

The remanufacturing process begins with a sound, undamaged engine "core" that is dismantled to the smallest components and then carefully cleaned, conditioned, and machined to OEM tolerance specifications. Each reusable part is also machined to original manufacturer tolerances. Throughout the process, the parts are continuously inspected for hidden damage. If tolerances are not maintained, the parts are removed from the process.

Long Block Engine


Long Block Assembly

The cleaned and reconditioned components, as well as new parts, are reassembled into what is known as the "long block" assembly. The long block assembly is the heart of the engine and, when installed, connects to the other parts of the vehicle, such as the exhaust, fuel systems, and electrical systems.

Vital Parts

Valves, valve seats, springs, and guides, along with crankshaft and connecting rods, are either remanufactured, resurfaced, or replaced. Cylinder heads are cleaned and resurfaced while cylinders are bored. Some of the new parts in a remanufactured engine include:

Piston and Pins | Piston Rings | Connecting Rod Bearings | Main and Camshaft Bearings | Pushrods | Timing Gear and Chain (Where Applicable) | Valve Lifters | Gasket and Seals | Freeze Plugs | Oil Pumps 

Restored to Original Specifications

Once assembled, a remanufactured engine must meet factory specifications during oil pressure, compression, and vacuum testing. If your vehicle is in good shape but your engine isn't, replacing your engine with a remanufactured one is probably the only way you'll have "new car" performance. Not only is a quality remanufactured engine restored to original specifications, the end product can be better than a new engine of the same type.
