I am very sorry to hear more issues discovered relating to the engine and most sympathetic. However more than once reading these posts over the months I am puzzled by the recurring comments to assume the the unknown is good enough. After the January 2020 posting about the JB weld in the crankcase I would think that the decision would be simple. Either fix the one element, button it all up and sell it without having to factually misrepresent the car or fully disassemble and inspect and measure every single element of the engine. To be surprised about more instances of hack work is to deny the known facts. At this point I would recommend one ascertain the entire condition of the engine, fix what is needed and have certainty about the rest. This will mean that once you do succeed in reinstalling the engine you will be able to drive with confidence. Otherwise, after all of this work you will always have a concern in the back of your mind, as to whether it may break for some reason at any point in time.
