Yes.  A 3 inch puddle is ridiculous.  A TD will drip and you must expect
the odd drop here and there. However, it is quite obvious that the rear
crankshaft seal/oil slinger is at fault, either by not having been
inspected and replaced if found wanting, or, the seal between the rear
bearing cover and the sump gasket, a crude asbestos rope type, has not
been correctly fitted, or has become dislodged during re-assembly. 
These seals are awkward to fit properly, and time must be devoted to
their correct placement, or you will get what you have, a pourer, not a
The correction is to remove the sump pan, and rework the rear oil
slinger/rope seal gaskets. It may be necessary to fit a new oil slinger,
and mate that by hand lapping to the crankshaft in order to obtain as
oil free a union as possible. There is also a new proprietary rear oil
seal on the market which will work better then the rope type. A word of
caution, however.  Make sure that the fault indeed lies at the rear end,
and the leak is not caused by some other problem such as a leaking oil
transfer pipe to the cylinder head.  This will be obvious by visual
inspection, when the motor is running.
If you have any further queeries, contact me directly. I speciallise in
the restorations of these treasures and, while I don't know everything,
I do know a bit and will be glad to offer you free advice.
