Hi. I would like to sell this car with Engine unit after complete regeneration: engine block, cylinder head and all parts washed in a washer using the latest 28kHz ultrasonic technology for best results; a second, ground crankshaft was installed; the main bearing bores in the crankcase were aligned; cylinder liners were replaced using liquid nitrogen or the liners were honed; new main and thrust bearings were installed; new connecting rod bearings; new seals; new or reconditioned connecting rods; new timing gear; a new oil pump; nominal pistons + new rings were installed; a new head gasket; a completely reconditioned and planed cylinder head was installed, with reconditioned valve seats, lapped and adjusted valves + new valve stem seals, and reconditioned injectors... The engine is currently in its break-in period, with 300 miles of mileage since installation. The oil and filter have been changed 3 times for a perfect engine break-in, and all filters are new. The complete engine reconditioning was performed by a professional company specializing in Mercedes engine repairs/rebuilds. All photos attached. If you have more questions please ask.
