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.

at least it's not the head! :) Too bad I spend a grand on machining though.

That sucks dude.

As far as what motor route to go with. Do you want to keep it more original? I'd go with the DOHC 4G6 swap but I am not conserned about originality.

If you wanted to keep it more collectable I'd stick with the truck motor.

How did you spend a G on machining?

well, it was balanced, the crank had to be welded and ground 10 under, polished, I had them put the pistons on the rods, etc. I just gave it all to them and they gave it back to me ready to assemble. And it was napa. :( maybe that was the problem from the beginning! haha.

But here's what I am going to do now. I am going to find a block, have it checked for cracks, if it checks out good, I'm going to have it bored .030 over and slap my innards into the fresh block and whip it back together.

Any suggestions if I do it that way?

Maybe dont use a block thats been bored so much next time. Use a stock bore or maybe .010 over.

I thought .030 was pretty standard overbore.
