I picked up my car today. They said they can't find anything wrong. They said the noise I hear is just "standard valve noise". They listened to another Crossfire and said it sounded the same. I'm still not convinced though. Had I not been late for a meeting this afternoon I would have made them start up another Crossfire so I could hear for myself. Does anyone else hear a lot of valve or rocker arm ticking during idle or when accelerating? I only have a couple hundred miles on it, perhaps the valves need to seat themselves during the break-in period?
