Oil in Manchette from the steering ger. Normal?

Hello.
I have an A8 4.2 Bj95 and an age-related hole in the left side of the steering gear. There comes oil out and then I also took the Manchette on the other side. Everything looked okay from the outside, but there's also some oil in the manchette, is that normal? Is it possible that there is always some oil in it, or does it have to be dry? When I watch the rack on the left side (Manchette is off), then always when I hit the right side a small spritzed oil comes out, just before the bar is the furthest outside, in straight exhibition and at left impact nothing is visible,... Is that normal?

Thank you for your help.

greetings
Carsten
