Use the stethoscope to listen for any clicking or clacking noises coming from the top of the valve cover, which looks like a long rectangular box (or boxes) on the top of the engine. Sticky valve and lifters noise, which will sound like a muffled clicking or clacking, will come from this area.

What should I do if my valve stem is stuck?
The valve stem will be shiny and have the diameter size of a pencil. Let the penetrating oil soak for several minutes. Gently tap on the top of the valve springs with a small hammer. Tapping the tops of the valve springs with the hammer will sometimes free up the valve stem shaft so that it can move properly.
