High quality valve cover gasket 11127587804 for N55

High quality valve cover gasket with OE number 11127587804 is a professional engine sealing part exclusively designed for BMW N55 turbo engines. Strictly produced following OEM mold structure and dimensional standards, this gasket is made of upgraded high-compression silicone rubber mixed with aramid fiber, featuring outstanding heat resistance, oil resistance and permanent deformation resistance. It can withstand the high temperature and pressure inside the valve chamber for a long time, effectively solving oil leakage and oil seepage problems caused by the aging and hardening of the original rubber gasket.

With integrated one-piece molding process and accurate positioning hole layout, it perfectly fits the gap between cylinder head and valve cover. It prevents engine oil from leaking out of the valve cover mating surface, and avoids oil mist escaping to contaminate the engine compartment. Once the original gasket fails, the vehicle will have obvious oil stains on the top of the engine, abnormal engine oil consumption and even risk of fire induced by oil dripping onto high-temperature exhaust parts.

Every gasket passes high-temperature aging test and compression sealing test before leaving the factory, with precise size to realize direct bolt-on installation without trimming. We have sufficient spot inventory, support bulk wholesale, mixed batch orders and global fast delivery. Highly recognized by BMW professional repair shops and auto parts distributors worldwide, it is an essential replacement to fix valve cover oil leakage for N55 engine vehicles.
