Hi, I have a 1981 380SL with about 25,000 miles on it. It runs great, but I noticed that lately I am getting a number of oil spots on the garage floor behind the pasenger rear tire. It looks like there are two rubber hose stubs coming out of the floor panel, and this where the drips seem to be coming from.

Any tips on what I should look for? Any check valves, PCV valves, etc. that should be checked, cleaned and/or replaced?

Thanks for all your help!
