I have had that happen before. I try not to fill it to the brim anymore. It is amazing how much that stuff will expand!! My '60 isn't quite up for the year yet. It is parked in the shop where I work on it when I get the chance. Hope to get at least another good spin before the white stuff comes to stay and the road crews start to throw the evil white stuff on it to make it melt.
