Really seems like a greater failure point than any other thing on these engines (besides spitting rockers out) and surprised Toyota doesn't recognize it and start pulling engines.

There were at least 20 failures just like that well before the recall ever happened. They sort of got overshadowed by the recall and people either never heard of them or forgot. Most were very early ones but a couple of others were later 13s. Think there was only one 14+ though.
Unfortunately there is no such thing as the "perfect" manufacturing process and my guess is that the robot that initially applied the sealant screwed up just as bad as some of the techs did later.
They had to have known about it but odds are it was easier (cheaper) for them to just let the few that may have had the issue through the system.
