Hi All, I posted recently looking for a mechanic because one of my J&T (based on DD) 6-71TIBs overheated and now needs a rebuild. I've been pricing out mechanics and of course it's not cheap. But I talked to a guy today who says he has a rebuilt engine that he would be willing to swap out for about the same as folks are charging me to rebuild mine. He runs a charter and says he no longer has a need for this engine. Any downsides of doing a swap that I should keep in mind? And what are the pitfalls of doing so. Once again, really appreciate the information.
