Recall that the IMS
is sealed from the crankcase and the engine oil by an inner seal. So I would assume it is relatively hard for large bits of the bearing itself to get out until the inner seal is really gone. The idea of the seal is to prevent a hot film of oil from getting to the bearing. So the fitment is designed to be pretty tight. Now it doesn't always work out that way and we all have seen pictures of where oil has intruded.
I only bring this up to support the postings that bits in the oil filter can be from many sources.
