Valve seal job on '72 280SEL 4.5L
 

What tools do I need to replace the valve seals, also what tools will I need to adjust the valve seals? I am just doing the valve seals right now, and I am going to see what will happen. Do I need the same kind of wrenches that you need to do this on a diesel? Could I do this basically with metric wrenches and sockets? Does anyone know of a website that has a how to guide on how to do this even if it is in a different Mercedes-Benz? I would imagine that most of them are the same. I will probably get a Chilton's guide to see if they have it in it.

Thanks for yor help
