News:
just add a bottle of Irontite or Bars leak
In that picture it looks pretty obvious. How did those other guys miss it? Also, what tool did Dave use to find it, again? I haven't heard of a head-check machine. Good choice to take it elsewhere, though. COuld be a blessing in disguise.
What place are you taking it to that is 3 hours away? I'm really surprised that you can't find anyone local to you to fix the crack. It isn't that complicated of an operation to do. Let me call a buddy of mine tomorrow and ask if he knows someone in the bay area that can do it for you. One place I dealt with when I was still wrenching in Campbell that was good is Gromm Racing Heads (San Jose). I would call and ask them if they do this type of repair or who they would recommend. http://www.streetperformance.com/parts/gromm-racing-heads-and-engine.htmlP.S. what hole does the crack travel across? is it a pushrod hole or? And - forgive me for my ignorance in advance - between whatever it will cost to get the crack repaired (I'm thinking generous 6-10 hours labor for the crack - drill-stitch-stop drill if needed-machine for seat insert-set installed height-surface-ceramic seal-pressure test), plus rebuilding and your travel time, wouldn't it be cheaper to get another head casting? I know you are going numbers matching but I thought I would throw that out there.
Head crack diagnosis: It's a scratch not a crack. Well that's good news to me at least. Machine shop wants a second opinion. But I don't think it has one. While I was there, I saw this 69 Hemi block I mentioned about. They're going to try and salvage it.
