ok for your winch, just reconnect it where it broke off, it'll be 6 inches shorter, but you should be ok, if you need that extra 6 inches, then you shouldn't be there anyways. And for the leak, dry it off and make sure it's not residual buildup from a previous oil change or something spashing on it in the garage. If it comes back run your fingers over it and you should be able to tell what it is, by the smell and texture. If you take it in, then put your 25's back on, more than likely honda will tell you it came from the stress of the motor running the bigger tires, or you trying to push a load of gravel. Just pussyfoot around the questions, and make then get their own answer. hope this helps you out.
