How about bringing it out of the fuel pump hole and then immediately enlarge it to a much bigger size to slow down the air carrying the oil. A windage tray could also help here. I am working on the prototype now BTW.

I took an S one, cut it and mounted it onto a fuel pump sized flange. It's pretty big at bottom- 1"? but over 4000 rpm the crank & rods chucked solid oil up there and it made like 007's Aston.
I was running a PCV valve but they don't suck that hard.
If you do it, I think it needs a plate baffle across it so the oil can drip back into the sump.

1" doesn't sound anywhere like big enough to me. The windage tray should stop 99% anyway.

You can't really make it any bigger than the hole in the block... unless you mill the hole out.
A windage tray would help I guess, but I've gone off those after what GR told me (no measurable power gain).
I might make another S type breather up with a baffle plate added inside the block, when I build the 1412 stroker....
