You won't do any damage to your engine with the hoses the way they are.
fwiw with the first can version with the steel wool inside, the advice from BSH regarding the "freezing contents" problem that occured in the depths of the North American winter was to route the hoses like you have instead of the other way.
....Are you sure, bacillus? If mine is wrong to the current instructions I think I'll be swopping them over after checking to see.
Yes, do switch the hoses as my original reply was simply meant to ease your fears that you may have done some harm by having your hoses reversed.
fwiw my buddy in the US ran his hoses like yours for a few thousand miles till I pointed out to him that they were not correctly routed. His car ran perfectly (with alot of logging done). He has now changed the hose positions.
Having your hoses reversed makes the catch can less efficient but not harmful provided there's little content in the can and the vapours/gases can still freely recirculate.
