Maybe there was a small scratch or something that requires additional sealing properties. Thoughts?

Despite what Wayne's book says, I would not use RTV anywhere on a 911 engine... I don't have another solution to offer however. Is it possible that the O-rings got crunched, twisted or otherwise mis-aligned during the install and therefore are not providing proper sealing?
