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.

Good hunting,
