Sudhir, In the aviation world, an aluminum engine case can be welded, depending on the location of the crack. Most times that kind of welding is only done at certified repair stations and it is very expensive. In the automotive world it's not worth the trouble. The engines don't cost that much, as would be the case with an aircraft engine. To be absolutely sure about that apparent crack, you could clean it up really good, then apply a dye-penetrant to the crack per the instructions and then look at it with a black light and strong magnyfying glass.That would tell you a lot. However, just looking at the pictures, off the top I would say that one is a goner. Might as well start looking for a new engine.
