I finally got around to installing my add w1 catch can today and I had a couple of questions for those already running one. How often does it need to be emptied during the summer and during the winter? Any problems unscrewing the reservoir to empty it during the winter? Are there any chances of the hoses freezing during the winter? I put them under the fuel rail, against the valve cover. Also, where would be the most appropriate to get rid of the gunk when I have to empty my can out?
