I got a small leak from the water pump cover gasket (94 STS). I replaced the gasket in the summer. I tightened down the bolts snug but I did not want to strip them. Each one feels tight. When the weather gets a little warmer, I will remove cover and try a new gasket. My other Caddy never leaked from this cover. When I removed that cover, there was no gasket. All it had was some RTV sealant. Do you guys use the gasket or just RTV? That gasket really doesn't fit in that groove so well.
