only leaks i see are the lines by the ex. valves. on 2015's the pressed in fittings have had this issue. above 15 the fittings are screwed in. the other place i see small leaks a lot are the small hose coming off the head going to the throttle body's. you will have to remove the driven clutch, mid air box, and maybe the oil tank or at least pull it out of the way with the oil line still attached. i bet it's one of these small hoses?
