1.Breather filter on the nipple located on the center iron.
2.Hose from the nipple on the oil filler tube, going to the large nipple on the bottom of the crankcase ventilation valve.
3.Another hose from the small nipple on the bottom of the valve, to a full time vacuum port on the intake.
4.One last little hose going from the top nipple of the crankcase ventilation valve to the intake.The manual calls for vacuum to be present only above 2000rpm,so that indicates that the vacuum signal to the valve is ported.If you cant find a ported signal(one that does not suck at idle) then try it with a full time vacuum signal.If your idle is poor with this method,youll need to get a hold of a delay valve to put in-line on the vacuum signal hose.

Man, that title does sound obsene! :)

I solved this issue by simply running a vacuum line from the nipple on the oil filler tube, straight to a nipple at the carb base (no pcv valve). Worked for me, but I know a lot of others insist that you need a pcv valve to do this correctly...

So, I did what peejay said to do. In the faqs it tells you. I ran a hose from the oil filler tube nipple to one of the nipples on my gslse intake maifold that sucks in air. Then I ran a hose from the center iron nipple to the pcv valve (92 dodge caravan 3.0l) to another hose to another nipple on the manifold that sucks in air. works great. All lung butter is gone. Now my idle is up a bit but, thats no problem to set.

does anyone have pics of this set up? on a 12a that would help me out
thanks

I already posted pics... I posted a pic of the crankcase valve in case you don't know what that is, and the nipples where you would route your hoses to on your 12A carb. The other hookups are real easy. Oill filler tube nipple to larger nipple on bottom of crankcase vent valve... and center iron nipple to larger charcoal canister nipple or a breather filter.

I checked the oil today like I always do at every gas fillup and even the pudding that I didn't clean off on the inside of my cap was gone. Maybe I'm crazy here, but the car feels smoother...???? Who knows, maybe it's just my mind liking the fact that I fixed something.
