Oil drain screw overturned !!!

Moin people, have the following problem, wanted to change oil yesterday and see, the screw turns, but infinitely and does not come out further. Now I thought to myself oil tank and look again, until I had the torx screws started was a murder work. So now to my problem, I can not get the oil tank further off, because the big engine handle or holder is under it. How do I go on ahead now ??? Motor lift ? But how ???? Is it enough that I have the two screws b Zw. Nuts solve under the two big rubber buffers or do I have to solve something ??? And how far can I lift it then. And does anyone know how to lift it ? From below without a lifter ??? For every tip I would be grateful. Drive an Omega B 2,5 TD ( BMW Motor )
