You can flush the cooler yourself and (if you're interested), collect any
metal flakes. You could do it in your kitchen sink, with a white towel over
the drain to catch any debris. Flush it several times in each direction and
see what comes out other than a bit of oil. After that, clean the sink
really well and throw away the towel, or you'll be subject to the wrath of
She Who Must Be Obeyed...

Flush it with what, water? Best to use a solvent to free up those buggers.
I know they sell a can that is used to flush transmission coolers; I had to
use one at OSH, when my transmission in my equipment van packed it in. If
not something like that, gas or kerosene, but at any rate, not water, and
not in a kitchen sink.

Damage like that and ANY indication of the possiblity of having metal
in the engine and I would do a complete teardown and inspection. A
teardown and inspection now is a heck of a lot cheaper than having a
catastrophic failure sometime in the future. There is nowhere that I
have to be or have my family at, that would cause me to put them
onboard the aircraft without having done a complete inspection after
an incident that might have put abnormal amounts of metal in the oil
system.

YMMV...but when it comes to my family, I am much more cautious than
normal.

Dag-nabbit, you're right. Not sure what I was thinking.
