There's no oil, no oil, no dust grain ect on my moth. but: at the ignition distributor driver side oil comes out at the bottom ! This oil drips (it is only minimal) down to the cracker or the transmission oil filler (depending on the driving method). So Ignition distributor out and O-ring changed (already 2 times) --> still oil.

Then the ignition distributor is fixed in such a way (white not as it is called) adapter piece and this to the cylinder bench. So this out and glued in with sealing compound (already 2 times)--> still oil!
Does anyone have any other idea where else there could be any? Since you don't see anything, who am I telling, I can only feel the oil, always drop it.Oh yes, valve cover seal and crescent naturally dense and dry.
