Get a flash light and a mechanic's mirror. Duplicate the problem and crawl under when it's doing the same thing and peer up into the block area. Cam plug or lifter galley plug is what it sounds like. A small stream is usually not present after shut off from the main seal. Maybe some dripping from residue but the stream action sounds like upper area such as cam plug and lifter galley plugs.

The back seal on the intake is bad for leaking on FE's, but yours keeps leaking after shutdown, so that should rule it out. It does sound like a rear seal, or the welch plug behind the cam.
