There wasn't any water in the jacket but there was plenty in number one pot, it's possible i may have to have the block bored out yet. i'll have to see once the pistons are out, i'll have the head skimmed and the crank either ground or polished depending on how bad it is so i'll probably have the block tested at the same time for leaks.Check the block carefully for holes and cracks seeing that its been parked up outside for a long time possibly without antifreeze.
Here's one I had to patch up lately...
Are you welding a mild steel patch to the cast block there? how do you go on welding the two types of metal together?
