anyone have theirs replaced? I mentioned it to the service tech today when I dropped off the car and he said he has never heard of the problem. I told him that mine had groves in them at 300 miles and my cousin Barry in Fl told me that a lot of Red Lines had this problem. He seemed not to impressed or concerned. He did comment on the extended crank time he experienced and I told him about the power surge at 4500 in 2nd and cold weather hard starting. He said that they would reflash the ECU and do the cam sensor seal recall. I go to pick up the car tomorrow at 5:30. He did say that he wanted a report back on the extended cranking time after the reflash, just so it wasn't related to other issues.
