2001my 257680 mi
Just received my Blackstone oil analysis couple of days ago.

GARY: Unfortunately, potassium went up, and so did sodium. These elements confirm there's coolant in the oil. This was a short run, too, so it looks like the leak is getting worse. Monitor for coolant loss, and use short runs like this until you're able to address the contamination problem. Wear metals don't look too bad for the miles on the oil, but we are seeing some increases since last time. Aluminum (pistons) and lead (bearings) went up, but these levels don't show poor wear... yet. Coolant could change that, so stick to 2K miles for now despite the good TBN.
Thoughts on where the coolant is contaminating the oil. TIA

 

What year and how many miles?

 

The very first line say 2001 257680mi

so the question is where is the problem? Is it a cracked block, oil cooler, or could it be the injector cups.
