Howdy fellow bolters! I've got a quick question regarding the oil bath air cleaner on my 53 6400's 235. On the (for lack of a better word) lid of the air cleaner there is a steel fitting that comes up and turns 90 degrees and faces back toward the fire wall. It looks like a vacuum hose or something goes on it but the motor has no PCV valve. My dad and I thought it might go to the rubber hose that runs through the firewall and into the cowl vent, but it was just a guess. Anybody else run into an OBAC like this or have any ideas? Thanks for the help!
