Mike Williams (el Miguel),
I think I did get a post from you about Ral. MB tech/wrench. 'Didn't have return address for you. 'Took my 81 300D to D & E Quality Ser. out near MB dealer in Ral. (401N?) in Feb for smoking-after-first-start-of-day prob. They did lots of tests/checks on it; replaced valve stem quides & several other little things. 'Found them very knowledgable and conscientious. Cost was much more reasonable than MB dealer!! 'Talked to Tim Mize, 919-872-7771. Good luck!!
Probably what my 300D needed as much as anything was some Italian tune-ups and occasional flogging - it has spent most of its life at significantly under 55-60 mph. It is coming around very nicely.
