Corby,

Once you get the valve cover off and look at the situation you see you do not have to remove the camshaft. The instruction, verbatim from the Mercedes-Benz technical manual, tells you to position the camshaft so the lobes are not compressing the valves. Then, without taking the camshaft out, you unbolt the little pedestals that support the "axle" the rocker arms move on, all together. Then, with all the fasteners that hold the pedestals down removed, the whole assembly gets lifted up and out of the area. The M-B manual suggests you matchmark the pedestals and the head to make sure you get them back exactly as they were originally installed. Should you have to replace one of the rocker arms it suggests you replace all of them, and the camshaft, so don't lose track of which ones go where. Good Luck, Jim
