Centrifuge Oil leak? Repost

My 2006 C230 has a slow oil drip from what my maintenance manual refers to as a centrifuge (at the rear of the right cylinder head). The oil drips on to the right exhaust at slow driving speeds and you can smell it inside the car. At highway speeds, there is no problem with smell. I am very mechanically inclined and I am wondering exactly what this centrifuge does in this case. It looks like it should be fairly easy to remove, but what parts are inside this piece? The manual does show to remove the air hose prior to centrifuge removal. There are no other problems with this car at 45k miles and we absolutely love it. Any assistance/suggestions are greatly appreciated. Thanks in advance.

Are there actually any moving parts or is this some type of fixed vane piece of equipment?

Could you post a photograph of this "centrifuge" as I'm confused what exactly you're talking about.

I don't have a picture, but it appears to be a black plastic cover on the rear of the right cylinder head. There is a black air hose that is attached to it and goes across the rear of the engine, I'm not sure where it attaches on the other end. I have a Chiltons Repair/Maintenance Manual and it says to remove the air hose prior to centrifuge removal. It looks like it would be easy to remove, but I don't want to remove it unless I know more about what is inside. I have done lots of repairs on various types of engines, but I have never come across anything like this. It's not any rush, but I eventually want to remove it to either replace the gasket or use a gasket sealer in order to stop the oil leak. Thanks for any help you can give.

MB of Austin tells me that this is an oil separator and that there is a Technical Bulletin to address leaks from this area. They add that I might also need expansion plugs. Anyone else know anything about this? They are going to get back with me, so I will forward anything I find out.

Yes, it's the oil separator... It tends to fill up over time, and will start leaking. I suggest cleaning it out thoroughly.

It has no moving parts, and basically just sends the crank blow off through a circular design that acts as a centrifuge.

So if it has no moving parts, are there any removable parts, or does it come off as one piece? Also, is there a gasket that needs to be replaced, or can gasket sealer be used?
I'm also curious about the expansion plugs, is that like a freeze plug? If this is something that just needs to be cleaned out, I don't think it is necessary to take it to a MB mechanic. Any other thoughts are welcomed, I am mechanically inclined, so I am thinking about doing this myself. Thanks.

It's all one solid piece, or at least on the M111 engine in my 02' Sportcoupe it was. Where exactly is it leaking from? Again, if you can get some photographs that would really help...

It is leaking from the bottom, looks like it's coming from between the mating surfaces, but it's kind of hard to tell. I've looked at it from the bottom, and it's really slow, but at slow speeds, you can smell it when it drips onto the exhaust pipe. Any pointers, or is that the only place it can leak from?

Found something for you... I would assume the centrifuge cap has a gasket that can be replaced.
