Remanufactured Engines FAQ

What is the difference between a used, rebuilt and remanufactured engine?


Used components are pulled directly from a vehicle – typically a junkyard vehicle – and generally not even so much as surface cleaned. There are no provisions for disassembly, internal cleaning, or inspection with a used component. Used or junkyard components may have high mileage and a poor maintenance history – a failure waiting to happen.  Many used or junkyard components come from a vehicle that was involved in an accident and may have unseen damage.



To rebuild is to recondition by cleaning, inspecting and replacing severely worn or broken parts. Serviceable parts are reused within the manufacturer’s acceptable wear limits. The quality of rebuilt components varies widely and many come with only a short term warranty.



To remanufacture is to make as closely to new as possible. All core material – head and block castings, crankshaft, camshaft and rods - are carefully inspected, checked against original equipment measured specifications for correct dimensional tolerances and precisely machined. Replacement parts are new or requalified to meet exacting standards and tolerances. Testing is performed to manufacturer measured specifications and original production standards.

When the core is returned, a JASPER Associate will determine the amount to be credited back to the customer’s account. The core returned must be a like-for-like Make, Model and Type, but not a junkyard core. Cores must be returned drained of all fluids and oil, assembled and attached to the same undamaged skid or container in which your remanufactured unit was shipped. Core must be returned within 30 days of the delivery date to receive credit. Full credit will be given unless certain damages and exceptions noted in our core policy are found.

The core policy on our reman engines varies according to several parameters. It is best to speak to one of our sales representatives for information as it relates to your specific application.
