Mine was just in for what I would describe as valve tapping at just over 20k miles. Receipt states all exhaust side hydraulic valve actuators were replaced, with reference to SIB 110907.
After this repair, still hearing intermittent tapping, engine temp made no difference. Dealer is now going to replace the entire cylinder head.
The rest of you seem to be taking this very well. The dealer has been great, but I'm shocked the car has this issue to begin with.
Don't get any ideas from my signature either, this car hasn't seen any track time or autocross. Never will, too heavy and an automatic, just no point.
