Ford Motor Company, Gearhead Engines, S&J Engines, Jasper Engines and Powertrain Products all make and sell remanufactured Ford engines. Most engine remanufacturers provide multi-year warranties, some without mileage restrictions, on their products. A wide variety of Ford engines is available from each source, with prices varying between vendors.
Ford claims to use only new parts in its remanufacturing process, while the independent companies claim that all parts used meet, or exceed, original equipment manufacturer specifications. All engine suppliers claim to use computer numerical control systems for production and testing processes, including cylinder boring, oil flow, seal integrity, oil pressure and compression as well as component quality.
