Well, Ive pulled the head. I am astounded by the lack of wear on the block. A small scuff on #3 cylinder wall...
The head? Toast... I popped out all of the pre chamber cups and found cracks leading up to the injector seat.
Also found 2 cracks between the valves. IF my head wasn't goosed with the pre chamber, would the cracks between the valves mean the head is stuffed? These cracks are between valves in each cylinder, not between cylinders...
