Long-Term Update from my original post:
Approx. 30k miles since first discovered, the amount of Potassium and Sodium in the oil is now low enough to not be shown in bold on the Blackstone report. The Bars Leak sealant was definitely helpful initially, and I have noticed a significant further reduction by using Mobil 1 High Mileage Oil. I suspect the seal-swelling agents in HM oil have been a factor in the latest samples.
I don't know the source of the contamination. My only purpose in this update is to report that managing a leak is possible.
