oil change reveals unknown debris/bits/particles in filter, what could they be?

[camouflage]

So today I changed the oil and filter on my 2008 xb12ss and I found some strange debris in the oil filter. The particles had a silicone rubber seal quality but I don't know what they could be from and I am worried if this is a warning sign of a potential problem about to happen!
I opened the oil filter to inspect the filter element for more debris and to confirm that the debris I had found wasn't any of the filter element glue.

Does any body know what these particles could be?

It looks like the silicone from the case half's. I wouldn't worry about it.

Have you done any work on your engine lately ?

Thanks Loose1 lets hope so! No Silverrider no work on the engine for a long time other than spark plugs, filters and oils. I have never removed any of the engine casings only the filler for the trans oil.

I would change your filter soon again , Just to check it out ,just to be at ease.

This^^^^

They aren't metal, there isn't much, and they aren't big. Just put on a new filter in 1000 miles and cut apart the one you just put on. I wouldn't even bother with an oil change. See whats in there.

This is sealing glue excess, no need to change filter or oil, this stuff will sit in the filter.

Thanks guys, I will change my filter in 1k and see if there are any more. A problem shared is definitely a problem halved ;-)
