Oil in MAF

1999 mercedes c230k keep getting oil in MAF sensor I have looked at other posts online and I'm am going to be checking the oil separator and the hoses but I have also heard that the crankcase vent valve could be faulty but I don't know where that is located in my car. Could I get some pics of where that is and if there is anything else I would have to take a look at to stopped oil from getting in my air intake. I have also heard from some people about the pcv valve but then I've heard that this part isn't even in the car. Appreciate the help pics would be helpful.

Check your air filter, if you are one that was bamboozled to put an oil laden air filter in the system you have found the source of the oil!!

Going back in time, and a long time ago, most vehicles had an oil bath air filter. Today they are the typical paper filters that just drop in, and have NO oil on the filter paper.
I think Plutoe maybe pulling you leg with his response, but you never know.
I doubt it is the air filter. This is what the PCV unit should look like
