Thank you for the replies. After taking it for about a 60 mile drive, the smell of burnt oil is gone. However, I re-checked the valve covers and there is a small seep on the drivers side. It still amazes me that the dealer wasn't able to find this the first time I took it in. I was unable to find any seeps on the passenger side, but I hope they go ahead and replace both of them if need be. I guess I should have known that the dealer was incompetent when they had to ask me how to open the keys...
