I've had this problem with my JGC Limited HEMI since I bought it in May of 11'. Happened at 2K while idling on a hill for 10 minutes. I assumed a break in sort of thing. At 8K it started happening when I remote started it. Most times it was on an incline, rear down, nose up. Dealer did first oil change, problem still existed afterwards. I now have 31K on the ODO, and problem still exists, frequently. TWO dealers have not been able to reproduce the problem. Jeep DM and RM Svc manager's have been involved and Jeep has NOT authorized the dealer to break into the engine or seals until the problem is visually replicated at the dealership. This is DESPITE the fact that I have it on video.
I have been in a loaner car for the last 40 days while the dealer has had it. They are now refusing to keep it any longer without the problem happening.
Im going to the dealer on Sat to either pick it up, replace with a SRT, or sell it to Carmax and take the depreciation loss and move on from the Jeep. Its shame, as I loved my 05, and the 11...but I don't want a problem when I hit 100K (which will be by the middle of next year)
Video shows blue smoke...this one happened to be light. Sometimes it was much heavier.
