Sounds like a box of rocks?!
I have had a couple of issues with my car lately and have been trying to diagnose them. The most pressing issue is a front main seal which I'll do this weekend. The other issue is a "box of rocks" sound that is getting worse. Much louder in the cabin then outside in the engine bay. I've realized that it only happens now when I depress the clutch or have the car out of gear. I'm obviously thinking it's a clutch issue although the 6-puck I have in there is functioning very well. Anybody have experience with this?
