After looking at how much debris winds up in the oil pan (which means it had to make its way from the other areas of the engine into the sump and through the scavenge side of the oil pump before it gets to the pan), just think how much similar debris is stuck to the inner surfaces of all those other castings as well as in the various bearings. The only way, IMHO, to properly handle such failures is to strip the entire engine and clean and inspect everything. Any bearing that is even slightly suspect should be changed. But how often do you suppose the MoCo or the ESP folks really do this, versus just replacing a few obviously damaged parts and buttoning it up, hoping it lasts just long enough to get you out of warranty or to have the ESP expire?
