Picture "Miller2" appears to show what looks like a lot of long term oil and grease buildup below the bearing area on the bottom and sides of the engine. Correct?

If so, do you think that this bearing had been leaking for quite awhile before the catastrophe?

If so, is there a lesson learned on checking out any oil leak immediately even if everything sounds/runs ok?

Sorry for all of the supposition, but its hard to make any firm determinations from just a few photos.
