So I dropped off the X5 at the dealership yesterday. I heard back this morning and they claim the misfires are from bad timing case gaskets. Can these gaskets cause misfires? I would think if these gaskets were bad, I would see puddles of oil and low oil levels, but I don't. The cement under the care is clean.

By the way, they want to charge me $1,740 to replace these gaskets!
