Great info. Need to refine my understanding of the pcv and crank case venting but your description is what I needed. I think your description of pcv on back end of valve cover is consistent with my setup. Not necessarily interested in giving up the air cleaner installed but it will need some repairs at some point and currently can't find the right ht filter. Currently the filter stands .25inch proud for the canister. Also if I bump into better condition cleaner or valve cover I want to be smart about comparability. Glad to hear of rarity. Could not find much info to this point after scanning to RPO list. Will open the linked pages more closely. Thanks again.
