Probably another newbie question, but I didn't find anything on the search for this.

I often hear a liquid sound, like fluid and air flowing in a pipe. The sound is coming from the floor in the front, on the passenger side. I guess it is the oil going to the oil coller which is near the front wheel. But the noise is pretty loud. I usually hear it when the engine is idle, at stop lights.
Is this normal ? Is there a way to remove some air from there ?

Or does it have something to do with the gas tank ?

Thanks,
