I'm sorry to hear your having so much trouble with your 6.0. I know some are running ok, but many are not. This 'joint venture' with Navistar has been difficult, and seems to have been getting worse according to old 7.3 owners who like their motors. At a time when profits and sales are so low, and the Super Duty trucks being cash cows with very loyal followings, it sickens me to see this truck and engine have so much trouble. Kinda like Miss America with hives. Not good. Hopefully the new diesel coming will be better. I love the idea of a big truck with a diesel getting better MPG than gas. Alas, there is no way I can afford one of these rigs, between the markup and my not winning the lotto.
