First, if you only hear it under a load, chances are it is valve ping. You could try a higher octane fuel to see if that helps. Regardless, since it is basically new, I strongly recommend having your dealer hear it and document the issue. That way if something happens when it is out of warranty, you have proof the problem existed prior to the warranty expiring.

If it is something different, let me know.

Well, have the oil pressure check if its within specs, if okay and you're sure its coming from the upper part of the engine. Get a doctor's ear and probe the valve cover and the injectors this will tell you something
