How it broke is an entirely different question.
Things we know it isnt- Bearing, crush washer, thrust washer,

Yup, magnetic.
It wasn't before, but is now AND caught this part. See below for more explanation.
I WAS running early 1.8 hydraulic lifter valve springs, then had an overrev earlier this year so we had to rebuild. I did not have a magnetic drain plug at the time. Of course we changed the oil, but we did not pull the drain pan. In the rebuild we used Supertech double springs with titanium retainers and SUBs. I agree (and hope) the theories are correct that this is a stock shim, and it broke earlier this year and sat in the oil pan until we installed the magnetic plug during the last oil change.
OR, we are wrong and it's a part from something else post-head rebuild.
It was stuck to the (now magnetic) drain plug; it's not copper.
