I know of a diesel shop that is awesome on any 7.3 or 6.0 Ford Diesel. Hems Auto and Truck Service in Bristol Boro PA. It would be a hike for you but Roland (the Owner) really knows his stuff! Prices are very reasonable as well! You can either google them or let me know and I'll give you his phone #. Tell him Joe @ J&R Landscaping sent you.
