Rebuilt Engines (Remanufactured Engines) - Quality You Can Count On
Rebuilt engines (or remanufactured engines) have undergone a complete restoration. This means that the basic block head, crank and connecting rods have been rebuilt remanufactured to OEM specifications . The pistons, rings, bearings, gaskets and seals, oil pump, timing and valve train components have all been replaced with new parts.

Many original OEM manufacturing flaws in the engine can be diagnosed and corrected, thus resolving the engine’s initial reason for failure. Expect the rebuilt engine to equal or exceed the performance of the original engine as the replacement components are more up to date than the parts they replace.
