This engine came out of a wrecking yard with no record of repair order. It was used for training purposes by me. I'm keeping the fuel pump and injectors and the accessories for cores and spare parts.. I took the head and other parts and accessories off. The engine block was not dismantled. The head was not dismantled. #2 piston had something go through it. Then engine is low mileage and has potential for an excellent parts engine, or if someone has connections and mechanically inclined, with repairs can possibly be run. John
