Question on Boxster Air Oil Separator

Thanks for the feedback re my Vacuum question, please see this diagram. I think the last guy under the hood may have taken all 4 "sealing bands" part 10 off the car and not replaced in the same location. I have sealed off the vacuum pipe hole with a blank plug similar to part 20 and reset CEL. lets see if it stays off! There was not a parts number list with the diagram so I am wondering why part 10 is shown twice but the rhs band does not have a hole. also the other bands have a different reference number but look like they are blanked off! Possibly its me being too detailed..... if the light stays off I will let you know... here's hoping!

part 10 is shown twice because each side of the plenum needs that sealing ring.

What JohnnyUK seems to be saying is that number 10 is called out twice but they are not illustrated the same. The one on the left of the diagram shows a side outlet with a plug.
the original question has to do with what is the outlet for? And why was his not plugged?

It is a test port to hook up a vacuum gauge during diagnostics. Why his plug is missing is anyone's guess, but the often get knocked out when people are working in the intake area or us pressurized water to clean off the engine.
