On the back passenger side of my intake manifold is a vacuum leak. It looks like a piece of rubber has rotted off. Is this a cap or hose? I cannot seem to find a broken hose if it is. This image shows something like a cap.
The top left corner of this image is what is in question.

Can you help?

If you mean the small port that points at the alternator circled in blue, it gets a cap in your vehicle. In other uses it is a vacuum source for accessories.

A fifty cent rubber cap fixed the problem. Thanks.
