Many used or junkyard engines were involved in an accident, immersed in water, or fallen off a cliff. Used or junkyard engines may have high mileage and there is NO maintenance history so you have no idea what could have happened to that vehicle's part prior to hitting the junkyard.
There are no provisions for disassembly, internal cleaning, or inspection with a used component. Used components are pulled directly from a vehicle – typically a junkyard vehicle – and generally not even so much as a surface is cleaned. A JASPER remanufactured engine is completely cleaned, disassembled, inspected, all components replaced, tested, and meets or often EXCEEDS factory OEM standards and backed by a Nationwide warranty. The engine history is not known and it is a failure waiting to happen. We get that question and the answer is quite simple, with a used engine you are gaining just that a used engine has not been completely inspected and cleaned with intensive testing.
