Omega B – Density of the steering gear

Moin people, have read me in this thread as well as other entries on the above topic: https://www.motor-talk.de/…/…pontaneous-oelloss-t5735850.html?… With me the oil also hung on the left carrier and was unsure where it came from. When I then pushed the hose with heat protection by side I could see that it came out with the adjustment screw. I first helped me out with a copper disc – also works very well over the oil tank. Questions: Is this e in the “typical” place where it leaks? Does the hexagonal screw serve exclusively the fei setting or can it also be “tightened”? Would an aditiv possibly be sensible? The flat mother actually sat bomb-proof on it and in the balance tank was also enough oil. Rather too much, since it stands above the second marking
