Wrong, they didn't fix the squirters, because in order to do that the entire casting would have had to be changed to get the squirters to feed from the main galley rather than share a tapped line to the main.

All they did was not put the groove in the girdle which accepts one half of a normal thrust bearing, and switched to a 4 piece thrust bearing. This "fix" was to allow what ever oil is there to get in between the crank and bearings more easily because only half of the circumference of the thrust on the crank was contacting bearing.
