I just don't understand so much desire to do expensive engine repairs when statistics show absolute success with seal repairs well into the third hundred thousand miles.

The job is 4 hours labor and less than $20 for seals. If you figure that the V/C gasket should be replaced about every 100k, then the extra work to systematically maintain the seals at the same time would only be 3 extra hours labor and less than 20 for seals.
