OK, one last update to this. I have noticed that the cold start surging I had experienced is gone.

Additionally I've traveled 450+ miles since the seal replacement and 150+ of those were city miles. My gas mileage changed from an average of 27.22 mpg to an average of 30.41 mpg. That is spread over city and hwy miles. The hwy miles are mostly at 3500-3700 rpm about 75-80 mph.
