Potassium, Sodium in oil sample, no Glycol
2005 Detroit 14 Liter. I am getting elevated Potassium and Sodium in my oil sample with no glycol detected. I am adding a couple gallons of coolant between PMs, so I am pretty certain I have a coolant leak. But where? I have considered the EGR cooler, but the EGR tube is blocked and EGR valve disabled. Also thinking oil cooler. Any help would be greatly appreciated. Iam going home thisweekend and would like to fix myself.
Is this a good question?
