If the expansion valve is leaking there should be oil around it. My 85 500SEL had a foam surrounding it and was soaked with oil. I would also suggest getting openend wrenches with two different angles. It can be done but it is really tight in there. My AC guy was good enough to lend me the tools I needed and new O rings. Have Fun
