First thing I would do is pull the valve covers and inspect. You can run the engine with them off also. Sounds like valvetrain to me. Poss wiped out lifter and cam. Ive seen that twice at the dealer.
pulled the valve cover and the rockers had a lot of play in the bearing shafts... side to side movements, and up and down only a couple rockers had that... spark plugs looked like its been running very rich...

i noticed it too...

what do you mean?
