Mike Busch / Savvy Aviation discusses a 15 year history of fatal accidents and emergency landings attributable to an oil filter gasket.
May not apply to your airplane, but may apply to someone you know.
For those who are short of time, an key paragraph....
It turns out that the NTSB has been bugging the FAA for 18 months to address this problem, but to date the FAA has been non-responsive. Finally, on November 30, 2020, the NTSB issued a formal Safety Recommendation asking the FAA to issue an Airworthiness Directive (AD) against these F&M/Stratus/Tempest oil filter adapters requiring repetitive inspections of these adapters to ensure that they are properly installed, have not come loose from vibration, and have not chewed up their gaskets. The NTSB also issued a one-page NTSB Advisory to bring this problem to the attention of aircraft owners and their mechanics. There are five different variations of the F&M/Stratus/Tempest adapter, designed to retrofit full-flow spin-on oil filters for just about every model of Continental engine that came from the factory with an oil pressure screen rather than an oil filter.
