Alright, after hours of research and finding almost nothing useful I've come here to ask for help/insight.
My car (CJAA) is sipping oil, I have had issues with my CCV before and in the past what I did was open up the little cover to get to the spring and diaphragm and i stretched the spring a little and sealed it back up, has worked fine for about 2-3 months. But now my car is starting to sip oil again and i suspect its the same issue.
After searching for quite some time I have found a rebuild kit for the pressure control valve portion of the CCV only issue is the full kit was shipping from Kiev, Ukraine and if you pay close close attention to the news you may know there is a bit of a kerfuffle going on over there so I can't order the full kit and instead settled on just the diaphragm from a UK company.
That being said I know this valve only closes under negative pressure situations like a very very dirty air filter. (mine is dirty and due for replacement but I don't think its dirty enough to cause this issue) That being said if I was having a negative pressure situation the valve would be closed, meaning nothing would be going back to the intake after the CCV correct?
SO this has lead me to believe that the cyclones (pictured in the yellow part of the diagram I attached) are clogged/dirty/not separating oil from the air. So im wondering if there is a non-destructive way of separating the grey portion of the diagram from the yellow.
Or if anybody else has any idea what might be going on id greatly appreciate it since my other two option are installing a catch can that drains its contents back into the engine somehow which would be a pain although I have found fittings that go from the CCV hose fitting to a 10AN HERE it says they wont fit our car but I saw pictures from another forum where they do in fact fit.
Also for anybody interested here are links for various parts:
Pressure control valve full rebuild kit (THIS rockauto one is not right i tried it)
www.aliexpress.com
Ebay link: https://www.ebay.com/itm/265454905060?hash=item3dce5866e4:g:VCwAAOSwgHthurC2
Just the diaphragm (fairly confident its the right size but not 100% sure though i do have one in the mail)
that being said if this is the correct diaphragm it should be the same one for valve cover part numbers; 03L103469, 03L103469S, 03L103469R
THIS one specifically is for the 2014-2015 passat by the looks of it Part number; 03L103469R, engine code CKRA
