If I had to take a guess, I would guess you have two different things:

1. There are some acorns that are cracked, probably no big deal.

2. There are scale insects or aphid insect in the tree, which cause dripping (oaks are know to get them)

And it may look like the acorns are causing the dripping, but its the insects.

Visit my site (shown below), go to ADVICE, then click Landscape Advice, then pick the topic on APHIDS and dripping. Much of the topic is also relative to scale, but you will need to read up elsewhere specifically on scale for control - if you feel you need to take action. (consult a local extension service, get a garden book, or use and search for "oak, scale" - there are several scale that oak get, and aphid are possible too)
