Abstract: A method of making a lubrication spray orifice for a valve actuating mechanism includes the steps of forming a dome socket for a finger follower of a valve actuating mechanism of an engine, forming a pocket in the dome socket and thinning out material of the pocket, and forming an elongated slit opening by expanding the pocket in a single lancing operation to lance a surface of the pocket to create a lubrication spray metering orifice.
