It appears to be a threaded hole with no bolt in it that's causing a slow oil leak.

Nothing missing from the hole, and the leak is above that even. More likely the valve cover since the whole head is wet

Re: oil leak from near oil filter.

My guess is that it is coming from the back corner of the valve covers. Run an inspection mirror along the edge of the cover. You should be able to spot where it is seeping out.
