Default y-block blow by..

hi guys! I need your thoughts? I have a 272 (1956).
that I rebuilt less than a year ago. I'm running "trips".
the problem I'm having is, I'm getting a lot of blow by
from the oil filler tube! I know the engine is mechanically
healthy, as I rebuilt it. I have a pcv installed in the top
of the block. (not the valley pan). the road draft tube
has been eliminated.(blocked off). I understand, the
oil filler tube also acts as a fresh air intake. but, something
I'm not doing right, because there is too much blow by
thru the filler tube, thus fumes are getting into car..
I know all you guys are extremely sharp! so, I'm sure
someone has a fix.
thanks!!
