cracked block

[Lifter]

can it be welded

 

[highflyn]

yes but it should be done by a welder that knows how to weld cast properly. Also it depends on where the crack is.

Yes your block can be welded! Have to drill out the both ends of crack first to keep crack from expanding. Grind and clean crack and adjacent area. Use ni-rod {stick welding} stich weld crack area weld max one inch at a time, stop and peen weld area for about 30 seconds to relieve stress and any spider cracking which may develop. Repeat process untill repair is complete. No pre-heat is required for this process. Works like a hot damm. Good luck.

How relyable will it be

 

[Hoochiebob]

A good weld will be stronger than the surrounding material.I think the real question is how good is your welder?
