A reconditioned engine comes up with warranty. It is one that has been stripped, overhauled and rebuilt with new components. The level of rebuilding in each engine will vary from one to the next depending on their individual requirements. But the overall aim of the process is to rebuild the engine closer to its original factory condition. Meaning you are getting an engine which now essentially, has 'zero' miles. A very big advantage is that they have already gone through the break in period. So why will you spend so much on new engines when reconditioned engines serve the same purpose.
I can recommend you a very trustworthy reconditioned Ford Transit engine manufacturer. Here is their website:
