Camshaft Lubrication Sprayer

The six lubrication sprayers are located internally in the upper portion of the cylinder block near the camshaft and have a guide pin for proper location during installation.‪

The EPA 98 (non-EGR) engine has one drilled oil passage hole in the lubrication sprayer – it is used to spray oil on the injector unit pump camshaft lobe. The lubrication sprayer for the EPA 04 (EGR) engine has three drilled oil passage holes – they are used to spray oil on the camshaft lobes for the injector pump, intake cam followers, and exhaust cam followers. See Figure "Camshaft Lubrication Sprayer" .‪
