Max Power about your XR6t I unfortunately work at Adrian Brien Ford, I have seen this happen alot. We had a staff member whos bought a turbo for her husband, it had some clutch problems they wouldn't do it under warranty - this caused a lot of problems around the place as the are so F***ing lazy when it comes to warranty work.(sorry you can probibly tell that I absolutely hate my job and work but this is the truth about warranty work in dealerships they make more money out of the customer than they do Ford)
I hope my warranty works as i had to come home from the cruise early as my clutch is playing up!
