yeah have known about the crack for quite some time...has been pretty good up till now. Most 05U blocks will open up when subjected to this power level for a long period. All the bogged launches twisting and stressing the block would have done it no favours.
I grouted it this afternoon...no more weeping coolant. Was going to machine up another block but didn't want to crack a good one. Engine back in by the end of the week.
