Benjamin.... What bloody awful luck, its everyones nightmare what you have just discovered.
That certainly looks like a standard quality, off the shelf 5204 bearing - not a ceramic hybrid bearing. It will be interesting in what Jake Raby has to say regarding the cause of assembly chatter

I think the minimum you are going to have to do is:
A) remove the bearing seals (are there 2 seals?) and determine how much wear there is on the bearing races and balls.

B) Get a strong magnet deep into the IMS tube to get any more debris out - papar towels won't remove all.

C) Do you have a magnetic sump plug? Even if you do, it would be wise to remove your sump plate and determine if there is any more debris laying in the bottom of the sump.

You MAY be lucky that the bearing seals have kept the metal shavings on the inside of the IMS tube, but I think you may have debris already in the system.
Best of luck - keep us all posted on the outcome of your problem.....
