Well I found the source of the leak, pin hole in the cylinder wall but I also noticed a couple of cracks at the two lower head bolt holes into the water jacket. If it was just the cylinder I’d sleeve it but the cracks at the bolt holes deem this block either a coffee table or a planter unless anyone has a fix for it. BTW this is a 340 block.
I tried to upload the pics of the bolt holes but it says they’re too large. Any help with it is appreciated.
