oil leaking dripping

[avguy]

I don't think this new leak is related to the valve cover gasket replacement. Sounds like either coolant or tranny fluid (assuming you have an automatic). Have you checked to see which fluid is going down? You need to get underneath with a light and find out exactly where the drip is coming from. But be aware that the source of the leak could be higher up, with the fluid being channeled down to where you're seeing it drip. If you still have that pos plastic thermostat housing, it's a prime suspect - they crack like clockwork and can pin-hole spray in any direction.
