You probably had an injector go bad and that is why your oil level was too high cause it has a weep hole that will spit diesel fuel into the crankcase. Normal oil change intervals is 16000kms or 10k in miles for the 6.4. Severe service which would include towing you would cut the mileage intervals in half. Call Ford customer relations and they should be able to resolve your concern. Was it a certified diesel tech that looked at your truck! I know that in Canada you have to be certified by Ford to work on a diesel if it has warranty on the vehicle cause I repair these trucks at a Ford dealer and it took me a bunch of training to get diesel certified by Ford. I hope you do not get screwed by the dealer that your truck is at, the 6.4 is not that bad of an engine either is the 6.0 IF they are maintained properly and not chipped. Hope this helps some
