They didn't really blow. They would slowly erode around the water passages until they "Weeped" or slowly leaked. I had it happen to me at 30K. I don't know which cars it effected but if you listen to Viper techs, owners and tuners Their are only two kinds of gen 1 vipers, those that have and those that haven't yet. If you have or are interested in a gen 1, if it has not had the gaskets replaced with the newer metal gaskets(if you replace it with the old ones, they will leak again)it will leak. Thats about a 3-5 thousand dollar bill. The gaskets alone are close to a grand.
