Blow by. Your rings and valve seals could be shot. Also check your PCV valve. Might want to do a compression test and a bleed down test.
Crankcase ventilation system problems, or massivly excessive blow-by. I'd check the PCV (or equivilant) valve first, but also examine the dip stick's seal at teh top for problems, too.
