Utterly befuddled with this car. It has 143k on it. Headgasket failed at 95K miles.
I suspected another failure. Car temp spikes up to 235* ish when run for more than 50 miles at a time, acting like it develops an air pocket in cooling system. I changed radiator in case it was bad cooling, no change in condition. It is consuming coolant and I can't see an external leak anywhere. Closest I can come is that the turbo banjo fitting has some dried coolant on it bit no sign of an active leak.
I checked oil, and found the oil level high on the dipstick by maybe 1/2 quart. I immediately stopped driving the car, assuming coolant was getting into the oil. I didn't see signs of water in the crankcase (like gunk under the oil cap or milkshake oil) but unless I am losing it I didn't overfill oil.
Here is where it gets weird. I drained the oil and sent it to Blackstone for analysis. I wanted to see if the oil showed bad engine wear to make sure that the engine was in condition to do another HG.
The results state they found NO coolant in the oil.

Calculated water % and Coolant % are both 0. Fuel % Shows .5, should be less the 2%.
As for Silicon, I live 6 miles up a dirt road. I am sure I'm getting more dust past the filter than most.
I'm at a loss for how to proceed. Change the banjo fitting crush washers and see what happens?

Potassium shows 0 (universal average 3) and sodium 11 (average 27).Jeff, You're concerns about a bad head gasket leaving coolant in the oil, but things look just fine on that front. Potassium and sodium shown coolant in our testing and both are very low. Wear metals are in good shape too, so there are no mechanical worries on the radar. Universal averages show typical wear levels for this type of engine on the oil. Silicon is a tad on the high side. Check air filtration and the intake for leaks/cracks, but this looks more like harmless additive or maybe sealer from recent work performed. Looking good at 144,132 miles.
