High quality engine overhaul kit 11110426591 for N55 B30

High-quality engine overhaul kit 11110426591 for BMW N55 B30 engine, complete OE matching accessories, wear-resistant and high-temperature resistant for full engine reconstruction

This all-inclusive engine overhaul kit marked OE part number 11110426591 is professionally customized for BMW N55 B30 engines, containing all essential gaskets, piston rings, valve oil seals, crankshaft and camshaft seals, bearing shells and rubber sealing components required for full engine disassembly and overhaul. Every single spare part is manufactured strictly in line with original factory dimensional standards and material specifications, achieving seamless assembly without trimming, padding or secondary modification during maintenance. The piston rings adopt high-strength alloy with surface nitriding treatment, featuring outstanding wear resistance and high-temperature deformation resistance, which effectively reduces engine oil consumption and eliminates blue smoke exhaust caused by worn original rings. All sealing gaskets and oil seals are made of high-performance fluororubber composite material, capable of resisting long-term erosion of high-temperature engine oil, coolant and gas, permanently solving common leakage faults including valve cover seepage, cylinder head oil leakage and crankshaft front/rear oil seal dripping. Metal bearing shells are treated with anti-friction alloy coating to minimize friction loss between crankshaft and connecting rod. The whole kit undergoes separate quality inspection for each component including high-low temperature aging, pressure tightness and friction durability tests before packaging. It fully meets the maintenance demands of engine overhaul after mileage accumulation, thoroughly fixes issues such as oil burning, power attenuation and coolant leakage, restores the N55 B30 engine to factory-standard working performance and extends the overall service life of the power assembly.
