I have been saying that improper sealant (even from the factory) was the major cause of the bearing failures in the early 13s but was shouted down by most that it can't possibly be that and had to be something else. Now we are seeing that it can indeed be that and nothing else.
I feel some what vindicated.

There does seem to be a pattern with timing cover reseals but I still am confused about how loose packing in the cover area would ever make it back to the pan or anywhere that would restrict flow. Excessive packing on the timing cover also wouldn't protrude into any galleries that I can think of. In the case of BestFRS's car they rebuilt the heads which means they would be cleaning packing and reapplying packing in an area that would easily make it down to the pan. Same for the recalls, they work on packing in the head. There are some areas on the block that could also protrude into oil galeries. But the block isn't touched on the recall or on the work BestFRS had done.
Edit: You know what, going through my pictures from my rebuild, the bottom of the timing cover is wide open to the pan. So yeah loose packing would get right into the pan and into the pickup filter.
