Are you sure it's engine oil? It could be a leaking tranny input 
shaft seal. You should be able to smell the difference.

There's also the cam tunnel plug. I hear that late cases use a 
different kind of plug, one what you can install without splitting 
the case. Maybe yours is backing out.

OTOH, a leaky engine main seal would leak against the back side of 
the flywheel and get flung outwards before it got to the clutch, 
while gear oil would follow the input shaft right into the center of 
the clutch disk.

When you install the engine main seal, make sure that the spigot on 
the flywheel is perfectly smooth. Sand it smooth with oiled wet/dry 
paper if necessary. The seal should be bottomed out in its recess, 
against the shoulder there. Don't just press it flush with the 
surface of the case, as many people will tell you to do.  

When you assemble the parts, oil both the seal lip AND the flywheel 
spigot.
