GMC and Hummer diesel engine, eight cylinders, 6.2 liter Detroit. Same engines as Hummer and GMC. For sale complete or as spare 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 as it consumes oil, but this does not affect its use. It starts slowly because the rings are worn. Whoever wants spare parts, we can dismantle it for them. Whoever wants the complete engine, we sell it. Bids must be made publicly.
