Not sure how/if that would work when removing metal pieces from intricate crevasses inside an oil cooler. If it was indeed ultrasonically cleaned, I am sure that "everything was clean as a whistle" - including the (first) left over metal pieces. Dammed near impossible to prove as the system is probably contaminated again. It is a problem that you initially were told that the oil-cooler and lines were replaced. In an ideal world you deal with "adults" that take responsibility for their actions and just do the right thing. I.e. just fix it if you made a mistake.
I'm sure this will be brought up by the builder once he receives the motor. I was billed for a new cooler and lines, the builder was told new cooler and lines were installed, yet they weren't.
