Can I weld on engine block?
Yes, welding up the cracks in an engine block can be possible. Well, as long as the cracks are located in a weldable area. Welding, when compared to alternative methods, makes a much stronger bond. Since part of the cast material melts with new blood (or metal, we should say), strength increases as you weld.

Why are there holes in the engine block?
engines are designed with holes in them. Mechanical holes aside, there are frequently a series of so-called “freeze plugs,” made of stamped domed steel. Freeze plugs are used to plug access holes, artifacts from the manufacturing process. Sometimes these freeze plugs will fail, leaking coolant forthwith, and must be replaced.
