I notice a "whooshing" sound when I start my car (especially when my top is down). It's constant after the engine is running. Once I put my foot on the clutch the sound changes but it is still there. It's very noticable. Today I started my car and could hear the "sucking air" sound. Once I pushed in my clutch which would usually quiet the noise slightly, I could hear a slight "clanking" sound. The typical "marbles in a can" sound. It's not real loud but it's there. I think it has something to do with the clutch cause when I push it in, the sound changes pitch and volume. What do you think? I am ready to take her in to an autoshop.
