The little nipple on the intake manifold onto which the vacuum advance hose fits broke off. The car seems to be alright without it. Can any of you think of a way to fix it?

 

How about buying a new one? Try a universal one from any parts store... can't be too much.

 

I am curious, why is the car running OK without it, I would think the car would accelerate terribly, not to mention the vacuum leak in the manifold.?

 

Works fine without it. In fact, it's actually hard to tell the difference, but I know my highway fuel economy will be a little worse. The B20 models have mechanical advance as well as vacuum advance. I have several other vacuum leaks and they don't seem to affect my performance either, it's kind of hard to get a B20 down. It just always wants to be awesome.
