2025 Mercedes-Benz EQE SUV AMG Car Leaking Oil

Some BMW 750i owners report experiencing oil seepage after replacing the upper oil pan gasket, particularly if the gasket was not installed correctly or if the subframe members were not removed during the process. This issue can arise despite following the procedure of unbolting the upper oil pan and accessing bolts through drilled holes in the transmission bell housing. Owners may find that if oil continues to seep post-replacement, a re-examination of the installation is necessary to identify any issues contributing to the leak. Additionally, ensuring that the bolts are properly torqued during reassembly is crucial to prevent further oil leaks. If problems persist, further inspection and potential reinstallation of the gasket may be required to effectively resolve the issue.

On the 3.9L V6 and 5.2L V8 it is often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
