I've never owned a car with that system. You guys make me look through 5-6 TSMs every time some little thing like this comes up! My previous post is correct. In 64 the 1V carb on the 196 OHV ONLY used a hose from the front side cover to the air breather with no PCV valve (64 American TSM, OHV section, page 11). Air flow in this systme is controlled "by a metered hole in the oil filler cap" instead of a PCV valve. The L-head and 2V OHV used a PCV valve. 65 used the same thing (page 14, 65 American TSM, 195.6 section). AMC went to all PCV valves again starting in 1966 (66 American TSM, 199-232 section, page 15). The 232 pulled air through the filler cap, the 199 and "Air-Guard" equipped 232s had a tube from the air filter housing to the valve cover for fresh air. It doesn't say, but I bet "Air-Guard" was a CA only thing. Of course sometime later (I'm not pulling several more TSMs right now!) all cars went to something like the "Air-Guard" system (air pulled in through the breather). -------------- Date: Wed, 24 Sep 2008 14:10:24 -0700 (PDT) From: Joe Fulton <piper_pa20@xxxxxxxxxxx> Through 1965 at least PCV valves were only found on the 196s with 2-bbl carb according to the TSMs I have. The 1-bbl installations had that funky "rebreather" system which pulled crankcase fumes back through the carburetor, like is shown on Bruce's pictures. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AMC.html (free download available!) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
