OK, the engine block seems to be cracked on the Volvo. So before we call the junk yard, I see that the JB weld site and the quicksteel site both mention fixing cracked engine blocks as something they do. anybody ever actually done that or know someone who did? I did use quicksteel to repair a hole in the metal of a refrigerator freezer box. The refrigeration guy assured me it was nonfixable, and wouldn't work. I tried it anyway and had him fill it back with freon...been working for three years so far. It is worth a try anyway, I won't haver that much to lose and much to gain.
