Foliver, lots of people have had to do the waterpump rebuild twice. I'm frankly amazed that I was able to do it just the once, and followed with a 600 mile day, a week or so later, without any leaks. It's not really easy to get that bearing/seal in completely straight. However, I understand that sometimes a little bit of coolant will leak initially and then stop on its own. How's your coolant level? If it loses a couple drops probably not a big deal. But I'm also a bit obsessive about some things so if it kept dripping, I'd give it another go. I know, not super helpful.
