BMW X5 oil leak due to gasket failure, common issue with 48i engine on BMW X5

Some BMW X5 48i owners report experiencing oil leaks due to gasket failure, particularly from the valve cover gasket, oil pan gasket, and rear main seal. These leaks are common issues in BMWs, with the 48i engine being more susceptible alongside other engines like the M54, N52, N55, and N63. Owners may notice oil seeping from various areas, including the oil filter housing gasket and main engine seal, which can lead to significant oil leaks from the bottom of the vehicle. It is recommended that affected owners have the leaky gaskets or seals replaced by a qualified mechanic to prevent further oil leakage and maintain vehicle performance.
