CLS 350 CGI (2008)
Good afternoon everyone !

My CLS is now reaching +220 000 kms (or 136 000 miles for our imperial friends), and I can often smell a little bit of burnt oil, coming from the PCV cover at the back of the drivers's side cylinder head.
While it seems to be a knows issue for our M272, I can't even imagine how to get it done, as it interferes with pretty much everything MB could have thought of.... Because of the CGI version I have, I can't find any history of how it was performed by others, except a magnificient thread by Conor a few years ago.
However, he had a S212, and I don't know if there are any differences between him and I in the process ? Do I also need to remove heatshields and the steering coupler ?
On my version, there seems to be an additionnal hose blocking the bottom screw.... (see video attached)

On another subject, I also happen to have some oil trapped in the valley between the two banks, and I don't see where it's coming from.... I do know the oil filter holder

Thank you all for your help and suggestions !
