Excess Blow-by

Excess Blow-by
I have had lots of blow-by on my stroker motor (4.625 stroke) and I have found several problems with the motor that I am fixing now; needs new crank pin, rods, and a bore out. The cylinders were badly scored, which I imagine helped contribute to the blow-by. I also use a S&S reed valve breather, which seems to work fine.
My question is can I route the breather tubes off the heads and back into the oil FILLER housing. This housing has a plug in it, and I thought it would be great if the mess just wound up back where it came from. Or would adding a little pressure to the oil tank cause problems? I don't think the pressure is that great. The bike is a 1995 road king.
Any thoughts on this? I really don't want to use panty liners in my carb cover.

Steve,
There is no need to get creative with the breather plumbing on that.
We have witnessed/corrected issues such as yours, many times over the years, and once addressed, those breathers are dry as a bone.
