C320 Oil Drip leak on exhaust manifold
2001 C320 55K miles
There are 3 black plastic cubes above the exhaust manifold. Oil seems to be oozing out of them and dripping about 2 drops per day on the exhaust manifold. The result is a deisel oil-burn smell about 5 minutes into every trip we take.
The driver side has the same boxes but no leak. There does not appear to be anything to tighten.

Those 'boxes' are your coil packs and not the source of the leak. I'm guessing the leak is coming from the breather box (I think that's what it is) that is above and to the rear of the coil packs on the valve cover. You need torx driver to tighten it down. Should be easy to replace the gasket if needed.

One torx was really loose
I put about 2 turns on the front recessed torx screw and saw it close the gap under the gasket. Then I cleaned everything up to see where it is coming out. What about the torx bolt-heads. What to they connect to?
I don't know
