Depends on which diesel you are talking about. A 1993 or earlier the glow plugs located outside edge of the heads below the valve cover. 1994 through early 2003, the 7.3 turbo diesel engines the glow plugs are located in the heads but under the valve cover. You will need to remove the valve cover to retrieve the glow plugs. Basically the non turbo diesels have the glow plugs outside edge of the heads. In all turbo diesels you have to remove the valve covers to get to the glow plugs.
