Ok I got a new headgasket after blowing my old one (after blowing old one I cam straight home from .5miles away, never overheated bad), and I'm still losing coolant somewhere. I don't think the head is warped because I don't seem to have a vaccuum leak, my rpms don't surge or anything. Is it possible I have a leaky hose, and that my system just isn't pressurized when it's sitting in my drive way, and I'm losing coolant while I drive?
