This seems like a worthwhile enough topic that I want to break it out as a separate thread.
My ‘73 1.7 FI car currently has these lines open, and I’m not sure if that will impact how the engine runs. Obviously everything ultimately should be connected but I’m not sure if it’s critical to the engine running properly or not. EDIT - wrong picture, sorry. |

That's the spark arrestor for the crank case ventilation. There should be a hose running from the bottom ports to each cylinder head and the top port connected to the port on the oil filler. Not critical and I think there is debate about whether it is good, but disconnected means you could have an open port on each head puking oil and an open port on the filler sucking dirt without having it hooked up or some alternative arrangement.
