Its good to know there isn't too many regulations. I have a radiator overflow can allready, need to tie down my battery though, its just sittin there now. Don't have an auto so it shouldn't be much of a problem. My rear main leaks a bit, not a whole lot but there always seems to be drips on my driveway, its not noticeable unless you like get down under the car and look, think that will be a problem?
