There's a bunch of them, just Goggle. Check out the process and a few sample reports to see if they will work for you. I used one about 10 years ago to prove to a builder that there was to much metallic floating in the oil after he looked at it and said that was normal for a fresh engine with only a few thousand miles. Turned out he did not machine the front of the block enough so the double roller chain finished the job. Good cleaning, new bearings, rings, and I was good to go. Engine now has 70K and no issues, does not burn any oil and gets used hard.
