Re: water leak

Hi
If the water is leaking out of the head, becasue the head is cracked or corroded, then replace the head and the gaskets. If the water is leaking from under the head, past the gaskets and the cylinder liner is OK but the block is corroded or eroded then you have nothing to loose by gluing welding or using a sealant, but to weld it the whole block and liner may have to be preheated, or it might crack.
