So removed the pcv valve and checked. It’s super clean and looks like it’s working. This is confirmed by reinstalling it and squeezing the hose which made the engine stall. So it is sucking air from crank case.

However I realized when I open my oil cap while engine is running there is quite a lot of pressure and it blows out gasoline vapor.pretty much constant. This made me belive that my rings are worn and the pcv system is just not enough to equalize the pressure so it’s pretty much stays open all the time. Does it make sense?

But the real question is should I do anything about this? My engine oil level does not increase se(last oil change February) so its only vapor leaking.
