Hi my car started making a kind of hisssss noise from engine. This happens when I travel for 30 miles on freeway and enter into city roads. Car does not make any noise when I first start. I observed this three times but not always. Can you please advice what could go wrong?
I will take it to mechanic but just wanted to get your opinion as well.
