2007 honda civic engine noise, gurgling noise when accelerating only 5-10 mph... on 2007 Honda Civic

My 2007 Honda Civic LX (1.8 engine. 4 cylinder) 23,000 mile on it.
Makes gurgling noise when accelerating, around 5-10 mph, after that it goes away. But the sound returns from time to time while driving.
I asked a Honda mechanic about it and they said its a common engines problem. If you happen to know the cause of this problem? We like to know. Thank you for the help and knowledge.

can you actually hear it outside the car or does it seem to be under the dash?
