Ok, so I am starting this project.
I've met Bruce McBurney (cool guy) and have already grabbed the McNeely(?) PCV jar instructions from his site. When speaking with Bruce, I asked him about some of the best parts for this. I was rather uncomfortable with glass inside an engine bay but he suggested a plastic bottle any ways. One from Sport Check that is supposed to be pretty damn sturdy. So I grabbed it the other day.
Next, the filtering material. One of the things that Bruce said that people are missing out on a big opportunity by only using filtering material and not a catalyst with/instead of the filtering material. He suggested silica gel because of the aluminum that gets released when it reacts with the hot oil air. (I could be mis-remembering some things, please bear with me, I'll be seeing Bruce again on Wed night to confirm).
I have a couple of questions. One, where do you buy silica gel? Two, if it's aluminum, I was thinking of using pop can tabs. Bruce did mention that Aircraft Aluminum would be best (due to it's magnesium content) but that is rather difficult to get I think. I could call up my local airport and see if there's scrap lying around :)
