Where is the vacuum section on this website? Sorry if I put this thread in the wrong group.
On a 1972 manual transmission intake manifold there is the screw port for the brake booster vacuum tree and below that there is a small tube that projects out of the manifold. OGTS calls it port B on their Where do the hoses go document dated 7/4/2012. They also state that the port B gets plumbed to the valve cover.
My question is, "Is this port open to the inside of the intake manifold?" I can not blow through mine nor can I see that the tube penetrates the manifold. I tried to put a small piece of solid wire through to unblock it but it would not go through. I dont want to drill it out if it is not supposed to be.
If this is supposed to be open to manifold vacuum then mine is completely blocked.
