when i brought mine wads told not to use the rocker cover breather and just to blank it off i forget the reason why but it seems to work ok
i've neva seen 1 like that though mate i would hessitae a guess at the angled one being the *exhaust* were a little filter goes on mine this is on the bottom with a long pipe onit and a mini k&n fiter tied at the sidr of the gboxthen the top 2 are for 1 from the crank case *original breather* then the rocker cover and the last one the return to the sump hope this helps mate
