I have not had to deal with oil-pan, or oil leaks on my W211 Bluetec to speak of so far, but had a little leak at the crankcase pressure control or bleeder valve due to ruptured diaphragm several years ago, so it's obviously unrelated to what you are dealing with!


You said you are using "the black gasket maker".
That does not mean much - could be almost any black RTV?

There are special Permatex / Locktite brand sealants made for this type of application, but the main thing is to make sure both surfaces are clean and free of any oil.

Here is a good paper gasket alternative that can also be used as a "gasket dressing".

But like all of them it needs some time to cure.

There may be others more suitable for oil pan gasket?
