So I just finished replacing the water pump, got everything back together, and was watching for leaks. I noticed the harmonic balancer didn't look right at all. Here is a you-tube video of the engine running. You might have to full-size the screen to see it well, but the balancer looks like it is running funky. I just don't know if it was doing it before the water pump change, but I noticed it right away now so I'm thinking this is new. Is one of my belts too tight?
