OK guys So the only one solution is making a new connection between the tho surface. :(
Finally I dont mind unfortunately this I have making this model since last year so since then I made a lot of modification and sometimes I dont remember the initial notions and proceedings. Anyway I dont import models those are original moi shapes I used to make those from something Rail revolv. (Thats why we need a nurbs based SubD :DDD ) and finaly I got two intersected ball what were filleted...as well as there were a lot of shell experiments...

And Michael thanks for the tips I havnt known that Shrinksrf command yet (cool tool) .
