Took the head off today and found this stuff:
Maybe the turbo's too big. I blame it on the turbo.
Milky coolant-oil mix on that stud that came out of the hole between 3 and 4. The block has little visible cracks from the stud hole to each coolant hole around it - the crack trifecta. The headgasket also failed, but I think it was because of the crack or whatever caused the crack.
I am happy to know what it is, and I'm thinking it wasn't
completely my fault, the block could have been weak there and perhaps even with a good tune it would have done this.
The pistons look pretty good, no visible damage, I bet the block is just fubar'd. So now the big question: buy someone's good shortblock or buy and build a wideblock 2.4 with dsm head and all that garbage? either way would be SO simple, but damn it if it doesn't cost an arm and a let.
