The oozy holes you describe sure sound the manifestation of Verticillium
wilt in oak trees, but could be any number of other things. The bugs you
describe in the tree (an pic thereof) are moths, probably gypsy moth or the
ilk. They are adventitious and not causative.
The tree sounds sick, and once a tree gets sick, opportunists in the (urban)
forest will find it.
IME black oak are not long lived in our area, relative to, say, red or
certainly white or chestnut oaks,
Can you post pics of the ooze and holes??
