cracked block can a block be welded

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. :welcome:

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 :smash: 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. :spank:

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.
