Serch on here and you will find lots of answers. In short, yes. Depends where the crack is. And how well the welder knows his business.

IMO, unless it's an expensive aftermarket block it's not worth taking a chance on welding it. I would look for another good core.

Bummer Dude, what block? I did that once to an engine, I kept the two pieces from the side as souvenirs. Sad part is was all fresh and still in the garage never made it down the road Like said about a new block as you only know about the crack you see. What if into the cylinder wall or other area? You could probably pick one up at a boneyard and make do.

Welding anything cast is a tricky thing. For practical purposes concerning stopping a leak, yes a block can be welded. For the purpose of repairing a block for good, no it can't be welded.

Please post the engine and other applicable things. We can't really answer your question intelligently. If you're talking about a small block chevy, then absolutely not... blocks are free on the internet every day. If you're talking about a rare early ferrari block that will only run as long as it takes to get on and off the trailer, then you can repair it with chewing gum.
