Down under the water pump there is a little hole that leaks oil when sitting, leaks more when it is hot outside. See pic, any ideas? Please Help... anyone!!!

The oil seal on the water pump shaft has failed, if it's actually leaking oil and not coolant.  Either way, replace both seals and carefully inspect the shaft and bearing for wear.
