Sorry for any confusion, but yes, both ends of the breather hose are disconnected when I blow the gunk out into the bottle (rather than onto the garage floor....). Ironically, my vent hose was very neatly routed and P-Clip'd by the factory during the chassis change, but I will consider re-routing with a permanent downhill slant if the mood takes me one day, but in the meantime I will just clear it out a couple of times a year using this method.
