I don't believe I could just write this off and take the loss. If I read correctly, the shipment was insured which should at least pay for any work necessary to restore to original condition and then get the engine to you. If the builder sold YOUR engine, I believe that becomes a legal matter. Accepting any partial payment of a full refund may complicate matters. This is indeed a difficult situation. I would start by contacting the Attorney General's office of the state where the builder resides. I believe there are commerce laws that have been broken here based on what I have read in your posts.
