Sounds like an intake gasket leak. Use 'search' and there are plenty of posts regarding the repair procedure.

 

is that the only thing it could be??

 

No, but based on your description (and without having a picture of it to look at), I would say it is the most likely. If you could post a good picture of the leak, it would help.
