Need picture or diagram of 67 327 emmisions/PCV hook up. At the back of the motor adjacent to the distributor is a cap with a hose connected to it. This hose runs to a PCV valve that is clip in a vertical bracket that is mounted on a stud on the second last bolt in the intake manifold at the back of the engine on the passenger side. What is this PCV supposed to hool to? The carburetor or the air cleaner? Does any one have a picture of the original setup? Thanks in advance.
