BMW N51 Oil Filter Housing Gasket

I'm replacing the oil-filter-housing gasket on a BMW with the N51 engine. If you're investigating oil around the filter housing, this video shows that specific engine setup rather than assuming all BMW straight-sixes are identical.

A closer look at this job

This BMW N51 oil-filter-housing-gasket repair addresses the seal between the housing and its mounting surface. It's commonly called an OFHG replacement or oil-filter-stand gasket repair. If oil appears around the filter housing on an N51-powered 328i, checking the actual leak source matters because runoff from adjacent components may look similar. Use this page to see the N51 job. The M54 and N52/N54 pages are useful comparisons but should not be treated as identical parts or procedures.
