I've noticed you track your car and am curious how is your headgasket going?
My HG recall was done on 04/26/19, and it included a new cylinder head. Not sure when notes were added that require sealant on the corners to prevent oil leaks, but I don't have any leaks to speak of. It only helped that the technician was probably one of the best (if not THE best) around these parts. Coolant level is stable since I got it back. Performance is outstanding. I love this car.
