well...
if 'swarf' means things like teeny tiny metal particles..
put it this way,
there BETTER not be any !

if I saw something like that in drain oil..
I'd cut the oil filter open ..spread out the paper element and start
examining with a microscope.

if the poster wants a defenitive answer..
send some oil out for an Oil Analysis.

the metal percentages in the oil sample very clearly said 'it's kaput'.  >

they tell you about 25 things about the oil too ..
coolant in it, fuel in it, about 15 or more metals...
had on 1.6TD that I knew was tired ...yep 'high chromium content
pointing to worn rings' which I knew anyway .

Very useful to do.  Oil Analysis is actually a regular part of really
good vehicle and engine  maintenance.
