Is that the crack(s) at the 2 and 3 o'clock positions on the combustion chamber? If not, would you be able to edit the photo with a red circle or arrow pointing to the crack?
Have you decided what you plan to do regarding repair (doubtfull this could be done where the crack is ) vs. replacement?
PS: This scenario is one of the reasons I did the full coolant system overhaul. I was afraid of a catastrophic failure resulting in a rapid overheat and blown HG or cracked head
PPS: Sorry if you've already explained this (I reviewed your first post), but was this due to an overheat situation? If so, what were the circumstances?
