cn90 is on a distinguished road
The video below shows a very comprehensive review of ALL possible oil leak sources for M54 engine.

Pay attention to time marking 2:45 where the person discussed the RMS, note the particular bolt I mentioned in earlier threads? It is wet with oil in the video. So I am very convinced that the oil at that particular bolt is from a RMS leak. If you do the CCV Mod, then it keeps the leak down to a minimum.

HTH.
