"I've seen where people us
"I've seen where people used a Dremel type tool to open the crack a little more nad just a bit to be able to get some JB Weld in there and drill the ends of the crack, to stop if from going further. You would want at least 1 inch of JB Weld on either side of the crack, need to push some in to give it some bite. You'll only need to buy a new intake/exhaust gasket and some JB Weld, let it cure for 48-72 hours in about 70-80 degrees and it should be good.
See when V6's and V8's crack they usually crack inside the V to which then lets water get into the oil ( not good ). Its RARE but does happen that a really bad hard freeze can crack through a cylinder, but it's usually hair line and doesn't cause much problems. Once that happens you would have to have that cylinder bored then sleeved. Still cheaper than a new block.
The only other concern is cracking the heads, which does happen from time to time.
Search JB Weld in the posts, you'll find your not alone."
