How common is a Porsche RMS failure and how do I prevent one?

This video discusses the prevalence of rear main seal (RMS) failures in Porsche Boxster, Cayman, and 911 models, particularly the 996 and 997. It highlights that RMS failures, characterized by oil leaks, are common but have become less so due to updates with newer, more effective seals. This video advises on proper installation techniques for the RMS, including using specific tools and avoiding oil or sealants on the seal. It also debunks the notion that RMS failures are due to heavy dual mass flywheels and warns against aftermarket seals and rear main seal bearings. Additionally, this video advises caution when purchasing low-mileage Porsche models that might have previously undetected machining issues leading to RMS leaks. It also notes that IMS flange leaks can mimic RMS failures.
