Blackstone confirms there are no titanium parts in my LS3, and no titanium in M1. But the GM Dexos oil does contain titanium, he said my reading is about what he would expect from a couple of qts of GM Dexos mixed in with my M1. Last oil change was at the dealer, none added during this run. Hmmm...
Also, he said that the high lead readings are unusual but not necessarily a problem. If the bearing were badly worn, we'd start to show copper which is underneath the lead. And lower oil pressure, which is not happening.
In other words, enjoy the car and see what happens on the next sample.
