GMC and Hummer diesel engine, eight cylinders, size 6.2 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 new piston rings due to oil consumption, but it does not affect its use. However, it starts slowly because the rings are worn. Whoever wants spare parts, we can dismantle it for them, and whoever wants the complete engine, we will sell it. Bids must be made publicly.
