would it leak only during the rain? and i mean heavy rain. It's like this white container that can be seen if you stick your head where pass. feet go.

as far as noise - it sounds like it's coming from dashboard and the speedo. It's not strictly clicking noise (not like click click click), it's more of a vibrating/clicking noise (so still click click click, except every click sounds like 6 clicks/second, and then a pause, and 6 more clicks, etc...) - that pause gets shorter as you drive faster.
