High oil consumption?

Hi guys, my wife's car has had an oil consumption issue for quite a while now, and it's usually at the rate of being almost dry on oil by the next oil change sometimes a little sooner. I work 2 jobs so it's very hard to really look at the engine, I kind of thought maybe it was the turbo seals leaking but there all this oil on the valve cover that seems to maybe coming from the little plastic box next to the coils, I'm thinking maybe it's got the PCV valve in it and some sort of oil/air separator, I have noticed the air filter has had some oil on it before when I was able to change it and I'm going to try and get time to change it again. I attached a picture of what the top of the engine looks like as of right now, whatever it could be I can replace it myself it's just finding it that I have an issue with because these Fiat engines are finicky, thanks guys!
