Here is Fords maintenance video (which I understand is included on a CD with all sales).
6.4 Maintenance Video
Click on "Lubrication System" on the main menu.
If your dealership tech can't service your 6.4 according to this bible, tell the service manager that you're going elseware until they get up to speed. A knowledgeable 6.4 owner will be the best incentive for the dealership techs to be doing things correctly until the learning curve has been completed.
