Any hoo... Here is the important data from the lab result, as well as what my rod bearings and crank looked like when I had the service done. The shop told me that I was basically 1 or 2 miles from spinning a bearing. There were hairs of copper in the oil, and the copper had started to create striations on the crank.

Thankfully, I was able to get the service done right before it blew up. Moral of the story. If you see numbers like this, schedule a service now, not later.

Thanks for sharing!
