I'm not a ford rep, but I do work in R&D for Cummins engine company. And i can tell you right now, they don't give handouts. If you drive the vehicle you purchased bone stock within reason and a part fails, they have no problems replacing the broken item(s). The second you modify anything, it becomes your job to prove that the mod you did, did not cause a failure. Recently there was a lawsuit over a warranty claim on an engine with a cracked block. We haven't put that specific engine into US trucks since early 2000's. We actually got an engine (same type customer had) installed the programmer, and installed it into a test cell to prove it created conditions beyond what the engine was capable of handling.
Seems crazy they'll spend 4 times more than the cost of your new engine to prove you broke it, but if they just go the cheap route and warranty you, they'll have to warranty all other claims just like yours and that could be ungodly expensive. I don't know if OP was driving dumb, had mods he isn't talking about, or if he is just super unlucky. But if there is anything they can confirm he did to cause the failure, most likely he's SOL. If they can't prove anything in his control caused it, he'll get it covered under warranty. They only cover the stuff they sell to you, used the way they tell you that you can use it. Nothing more. Curious to see how this all pans out
