GMC and Hummer diesel engine, eight cylinders, 6.2 size, Detroit. Same engines as Hummer and GMC. For sale complete or as parts. The heads have been serviced by replacing new valves and a full inspection of the heads, they are sound and have no defects. The diesel pump has been refurbished and an internal repair kit has been replaced. The engine is running and needs the piston rings changed, it has oil consumption but it does not affect its use, except that it starts slowly because the rings are worn. Whoever wants parts, we can dismantle it for them, and whoever wants the complete engine, we sell it. Bids are to be made publicly.
