Also something to consider
I have a small coolant leak in one of my 235s that’s right in the middle of a flat spot on the side of the block, not even at a seam or ridge in the casting
So a defective block is possible too
Just like 59rebuild my leak was only noticeable after I cleaned the rust out the block, before that it was dry (oily and dirty tho).
