A couple years ago I had the engine overheat. After getting the radiator repaired, I ran a short oil change ~500 miles. Engine was running fine. I haven't put a ton of miles on, so I thought I'd send another sample to Blackstone - about 6,000 miles since the last analysis (multiple oil changes). Here's the summary:
Wear metals are generally a little better than last time, even with the longer oil run, but the increase in potassium is
somewhat concerning since that can show a little coolant in the oil. It's probably not enough to notice the
coolant level dropping or anything like that yet (so you've caught the leak early), but do monitor to make
sure it doesn't get worse and stick with short oil runs for now.
Potassium is up to 16, up from 8. Universal average is 4. Complete report is at http://www.gmcmhphotos.com/photos/member-galleries/p59872-oil-analysis-report-jan-2016.html newest readings in the first column.
Do I monitor this, try to retorque the heads, change to an external oil cooler, or some other recommendation?
Thanks in advance.
