I'm just learning about engines. I've got a question that I hope someone might be able to help me out with. I've got a 394 olds. on the back of the manifold by the fire wall there is a valve. When I took off the valve cover, there is this cylinder type sleeve / tube that is inside of the manifold. It spins around and if I turn it to where the lip is on the bottom, I can make it fit tight again. Can anyone tell me what this is or where can I find out?

Totally lost....but trying anyways.
