Removing 30-year old vent
Have a CGa from 1978 with an oozing vent. Obviously the Schrader pin is shot, but I'm guessing the body is gone as well. Or do you think swapping the valve pin might work?
If removal is necessary, what do you think the chances are that it will come out in one piece, threads and all? I really don't want to be fighting with it at this time of year when it's 20° out.
