Cam plugs, centrifuge cover, and vacuum pump
Hello everyone,
I'm looking for a little advice on parts and videos for replacements. I recently purchased a used W204 with 60k miles on it and it seems to be in pretty good shape mechanically. I had the car at the dealership for a wheel alignment and they gave me a small list of some recommended parts that need to be fixed, mostly because they are leaking oil.
They said the cam plugs, centrifuge cover, and vacuum pump need to be replaced. I've already watched a few videos for the cam plugs and vacuum pump and can manage them myself. But I can not find anything on the centrifuge cover.
So here are my questions for the group:
1) Since all these parts are leaking oil, do I need to drain my oil first before replacing them? There was no mention of this in the videos that I've found.
2) Can anyone recommend a video for the centrifuge cover replacement?
3) The cam plugs (and possibly the centrifuge cover) are just simple, non-mechanical, plastic parts. What are your thoughts on aftermarket replacements from someone like Dorman?
4) Does anyone know the part numbers for these parts? I'm not great at finding part numbers without ripping the part itself out and Mercedes has a new policy where they will not give out part numbers.
Thanks all, any advice will be helpful and much appreciated.

Thank you IGB, that other post was very helpful. And I'll stick with factory parts. Just to make sure I'm understanding where all the parts are located in this image, the two smaller circles indicate the cam plugs, the larger circle on the left indicates the vacuum pump, and the larger circle on the right indicates the centrifuge cover. Is that correct? That's the best I could tell from that image and some videos anyway.

For added reference, the "centrifuge cover" is often referred to as the "oil separator" as well as "crankcase ventilator".

An additional update, I made a diy for the replacement of the oil separator/centrifuge cover (I titled the thread with both so anyone can find it).
Here is link to the diy for anyone who runs into this thread first: https://mbworld.org/forums/c-class-w...separator.html

Centrifuge bolt inside cover
If you want to replace the centrifuge too the bolt is left handed threads. Don’t twist the wrong way. It will sheer off ( I learned the hard way). Now I need help on how to remove the broken bolt
