When I turn on my car, it is heard as if a liquid passes or moves, it is a matter of 3 to 6 seconds, and it is only when I turn on later, nothing is heard, that I detected yesterday and it had never happened to me before I checked levels of oil and everything well in fact all the witnesses of the board are well do not mark any alert. They can help me to guide me what it can be, I will take it to the agency at the end but it would not be enough to give me an idea
