here's the original thread;

Got the Blackstone report today
here's what they said;

KEITH: It's not unusual to see high wear from a rebuilt engine. Universal averages show typical wear levels
for this type of engine after about 2,600 miles on the oil. We are a little concerned about potassium and
sodium. Potassium could be from the rebuild process and sodium could be harmless oil additive, but the two
can also show coolant. Lead, from the bearings, seems high, even for a new engine, and that's where
coolant tends to attack first. If you're not losing coolant, it's just something to monitor at this point. Check
back in 500 miles to monitor.
