Yeah, I am not sure if any seal is going to last once the bearing sees an over temp in the engine. After the testing I did, any rubber seal "enclosed" in the engine isn't going to make it with the higher temps these engines produce. This is one of the reasons I am cooling the ambient temp. around the engine and cooler oil pumped directly into the oil pickup. I am not sure what it will do with overall temp. but if cooler oil makes it way to the internal areas, I am sure life expectancy of the engine will increase.
Another thing I am looking at is hacking one of the side vents and putting a 911 oil cooler/fan behind the rear wheel. These engines move allot of oil and need a big cooler to accommodate that, not the puny one they have installed.
