  • Cracked Head...Now What???

    Just got word from the shop that was suppose to fix up my valve seats that the head was cracked.. I don't know what to make of this since there was absolutely no leak to begin with, wouldn't a cracked head for surely leak? Now that this bomb was dropped on my lap, I'm asking for anyones input on what should be my next step. (Vehicle info 4.2L 258 81' CJ7) Anyone have any good info on some contacts for a remanufactured head? What should I do????

    I'm sure that a quick look through the search would find either a head or a full engine that someone wants to give up. With the number of guys doing 350 swaps here, there is bound to be someone with a head sitting in their garage gathering dust.

      a crack isn't nessesicarily a broken in two crack. a hair line fracture is also a crack. if it's in a low stress area i'd JB Weld it. then again, if it's in a high stress area i'd JB it. or you can probably find a new head. if you've got a couple bucks, i'd recommend a 4.0 head. it's an easy swap and well worth it.

        You can get a head from a junk yard and and have a valve job done. With the wounders of the internet, they can find one just about anywhere.
