There has been a lot of discussion about issues with tapping noises in the valvetrain, and some '12s have had the problems manifest as check engine lights. I would like to suggest that anyone with a '12 who is concerned about the issue but doesn't have a check engine light either perform a leakdown test or have one performed by a mechanic (preferably not at a dealer).
Hard to imagine you have a real problem if leakdown results are good and no oil consumption or check engine light. But if a lot of '12 owners are showing bad or marginal leakdown results, particularly on cylinder #2, that tells us something.
Would be great to see some results posted. There may be reason to be concerned even if you don't have a check engine light, leakdown results could be instructive.
