Hi super chuck...think your PVC Fix might work, in the same location as the krankvent. I bought the Bunn breather, again, A hundred bucks, it still burped oil. My solution was to buy some window screen, roll it up like a cigarette , stuff it in the tube just above the nipple. At the timing case nipple, I had a hose about 2 feet long, with a cheap little filter. It was the intake. To test it you blow air through the hose into the timing case nipple, and the air comes out at the crank case nipple, up through your PCVvalve over the frame under the seat.
You will have to experiment with the amount of window screen cigarette " baffle" to use in the hose to prevent oil burping through your PCV valve. Up under the seat and out wherever

It worked good , but last week I got out my drill ....just had to do it...the old style breather...pics next week
