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 |

Thanks guys. This isn't the best picture, looks like a valve but confirmation would be good.

QUOTE(robkammer @ Dec 9 2021, 07:50 AM)  Thanks guys. This isn't the best picture, looks like a valve but confirmation would be good. That is indeed an early crank case vent system/PCV valve. It looks like your intake plenum is the later style though (based on the thicker throttle cable bracket) and that presents a bit of a problem as the later style does not have the port necessary to attach the CCV to it. You can verify this by checking the two ports on the side of the plenum. The late style has a large and small port, the early style that is needed has two larger ports. Not sure what airbox you have but you will need the matching early style as well.  |
