Original quality valve cover 11128631745 for BMW B48T

This original quality valve cover with OE part number 11128631745 is exclusively engineered for BMW B48T engines. Manufactured in strict accordance with OEM material and dimensional specifications, it can directly replace the original valve cover during engine maintenance without cutting, drilling or secondary modification.

The valve cover is integrally formed with high-rigidity glass fiber reinforced plastic, featuring outstanding anti-deformation, high-temperature resistance and oil corrosion resistance. It effectively isolates engine oil and blocks oil mist overflow, fundamentally resolving oil leakage, oil seepage and carbon accumulation issues caused by aged, deformed original valve covers. It comes equipped with a built-in integrated PCV oil separator, which efficiently separates oil and gas, prevents excessive crankcase pressure and avoids abnormal engine idling and intake system fouling. Matching high-density rubber gasket provides lasting compression recovery to maintain stable sealing under long-term alternating hot and cold working environments.

Precision injection molding ensures all bolt holes, pipeline joints and mounting contours fully match OEM parts for tight seamless assembly. Every finished valve cover undergoes air tightness and pressure leakage testing before delivery to eliminate hidden oil leakage faults.

Widely adopted by professional engine repair workshops, this is an essential reliable overhaul spare part for vehicles fitted with BMW B48T engines compatible with part reference 11128631745, maintaining clean engine internal environment and stable operation performance.
