My 05 S80 T6 sounds like a tub of rocks is bouncing around when I start it, been told it threw a rod and I need to either rebuild the motor or replace it. I would like to know where I can buy a replacement motor, or any recomendations on what I should do at this point. Thanks

 

If your handy and have the tools you could rebuild it. But that takes a lot of time and might cost just as much to have a mechanic install a used engine.
