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.
