How many miles/how much wear are on the other rings? Takes a lot to break one-- original from a '93 block are definitely a bit more fragile than a new one of course.

Haven't tried them but viton sets from Atkins look like a good value.at around $60 with viton outperforming rubber compounds in every way possible like heat and wear resistance and resistance to degradation
