I'm in process of cleaning up all of the electrical and vacuum lines in the engine bay. The car does have a check valve of sorts, maybe a PCV. I read differing accounts of whether or not a 74 should have one or should it just be plumbed without?
And I've gotta say, it sure looks nice in there without any vacuum lines! Rob |

Rob You should run one IMHO. Otherwise stock up on valve cover gaskets. |

The 74 was a passive vent system into the air cleaner. I prefer the positive flow on my motors (like the 73) but if passive was good enough for Porsche/VW... You need it. 1) you don't want to vent that to atmosphere 2) gaskets 3) engines last longer if those gases are not in there too long. |
