@that_mex_mechanic: Duramax LLY Engine Assembly. This engine suffered from thermal overload resulting in a melted piston. The block got bored 0.030in over and honed. With new pistons and bearings, this bad boy will be whistling across the city in no time🔥. Follow in you enjoy engine building and ASMR #diesel #enginebuild #mechanic #asmr #dieselpower
