Title pretty much says it. I just started hearing it today. It's not very loud at all. I could just hear it with the windows up. When down it's slightly louder. I only heard it while sitting still with the clutch in or in neutral at a red light but the car is pretty loud while driving. Tranny shifts fine. car drives fine. A couple of synchros were changed about a year back and all fluid was replaced. I have had the infamous throw out bearing chirp for a few months now but that's it. Any ideas? Think it's something to worry about?
