I would determine that it is in fact the crank seal.
The in line VW engines are known for the oil pan gasket leaking at the
back of the engine over time. The cast iron block is open on both ends
for the crankshaft to be installed. There is two aluminum cover plates on
each end that hold the crank seal in place and pick up the gap between
the cast for the oil pan to bolt up to. Time and temperature differences
in the two metals fatigue the gasket.
I have had two engines with this section of gasket (approx. 5 inches
long) with 1 inch openings on each end.
The leak in this case is usually most visible after the engine is shut
off as the oil returns to the pan. It leaves a nice sized puddle of oil
on the ground and is quite messy in the back lower section of the engine.
This is why you get a crank seal diagnosis (Also big$$)
Replacing the oil pan gasket is simple. A little challenging in the area
of the leak but can be done on your back in the driveway.

I have never yet had to replace any seals in any of my 5 in lines or any
I've had in the past, so my guess is a incorrect diagnosis.
The valve cover gaskets can also leak an incredible amount of oil in some
strange places.

Both a easily replaced. Just keep the gorilla away when tightening these
bolts. Get a Bentley for the torque's and future obvious reasons, and
recheck them after the engine has reached operating temperatures.

Let me know how it goes.
