Fe450 pushes oil from valve cover

Hello! Husaberg FE450 2005 seems to have a problem.
Engine ran perfectly but pushed oil trough the breather hose from valve cover. I got sure i got right amount of oil so it wasnt about that.

Then i did the engine repair (piston, crankshaft, crankbearings and seals and new waterpump).

Same thing repeats. I were worried about wornout piston but the wasnt apparently about that.
Tips and advice would be great if anyone had the same problems

Sorry for amateur english.

Has the breather hose been modified or is it still attached to the frame backbone as originally equipped?
