OLM was at 19%. Filter was NAPA Gold 7060.
Blackstone Comments:
Copper improved this time, but lead is going the other way. Lead might be a sign of bearing wear, so it's an important one to watch, but there's still a chance that the lead in your system is just coming from the new radiator you installed prior to the last sample, rather than any sort of bearing issue. Hard to say for sure at this point, but keep an eye on the oil pressure, and stick with 9,000-mile oil runs for now. If lead continues to increase, and especially if copper or other metals increase, it may be an issue. Hopefully, though, it will go away on its own soon.

The lead creeping up is a concern. The next UOA will show if it is trending upward.
