Is it worth changing a water pump on a 93 Saturn with 170K?

I have a 93 Saturn SC1 coupe and Im pretty sure it%26#039;s gonna need the water pump replaced. I paid 600 for it in november, and i%26#039;ve gotten almost 10k out of it without a major issue but the rings are shot i think, it blows oil a lot.Is it worth ripping it apart for the water pump? Any suggestions would be great.|||We handle HOW, it%26#039;s up to you to provide WHY..|||no
