Yar...........on my GMC 228 the draft tube is the oil fill tube as well.
I used the stock draft tube, modified it, by cutting it in half, turned the top welded it back together, use the draft inlet as the PCV valve location. Installed a valve cover with vent.
Send me a PM with your email will pics.
