Oil loss on the right / gear side

Hello, after I had had the clutch replaced before 3000 km I now have to notice with horror that I have oil loss. During the clutch change two sealing rings have been changed with ( 9458178 / 6843481) now does not know the exact description of the rings. I suspect that the oil trap / flame screen are the culprits, see photos, on the oil tail stick he siffs out and steams at running engine. My fear now, it can be that the oil trap is dense and thus the sealing rings which are out now due again at the clutch change would be? He has run 314,000 km, whether the oil trap / when you have been changed times, no idea. Have times attached a few photos, someone knows the problem and knows advice. Thanks in advance.
