Once the wear has occurred over time the tolerances between the rod and the bearings loosen up and the friction decreases somewhat...so less lead/copper would be spun off. I'm not remotely an expert in this area but based on the research I've done...I don't think this report can be read that your bearings are in great shape. Maybe they are...maybe they are not.

Not suggesting my bearings are in great shape since the only way to really know is to take them apart. I did the report because someone asked me about it a while ago and I said I'd do it when I hit 150K. Plus, this gives more data for those who are interested and said my engine would explode...80k miles ago. |
