Intake Manifold Secondary Butterflies - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I am going through the process of removing all my emissions from the intake manifold, when I came across these. Now should I remove the actuator and leave the plates inside the runners, because I am guessing as long as they dont have a vacum line they'll stay open right. Please correct me if I'm wrong and tell me what I should do.
Thanks people

Remove the plates too, or even better remove the actuator rod as well. It's simple, and there's plenty of info on it if you use the search function.

If I remember right they are closed untill vacuum is applied. All you need is some anaerobic sealer and a small oil gallery plug to plug the hole left when the actuator is removed. You take off the screws holding the plates onto the rod and a screw in the center then pull the rod out.

Let me explain myself again. I know how to remove them, I just forgot to do so and now it's kinda late. I did remove the rest of the emissions stuff, now the question is if I plug a vacum source to the actuator of these butterflies from the Intake Plenum is it gonna operate normal?
Thanks

They are normally open.
Just remove the plug or the vac source and thats it.
