Used engine is an engine that usually was removed from a wrecked car.
It can be just fine if the owner of the former car it was in maintained it but that can go from just fine to why did I buy this piece of crxp real quick.Usually you get a warranty,that is to say-the people that put your engine in will get a warranty for the used engine.But you have to make sure they pass that on to you.Things to watch out for are odd noises,oil usage or coolant loss indicating head gasket,or possible engine damage.
Remanufactured engines are just that-used engines that have been rebuilt.These engines should all come with a good warranty that is valid as long as a good shop or mechanic installs the engine correctly.
