This one, thankfully, isn't my car. It's one that came into the shop here with a ripped up timing belt. It still has the balance shaft module at 200k miles!Sodium is indicative of coolant as well as potassium. 95 ppm sodium, elevated viscosity and water could indicate coolant migration into the engine oil.
Overall it looks pretty bad, however it’s just one data point. You could tear down the engine and do a rebuild, or just keep driving it and re-sample at a shorter interval 3-5k and see what it says. Could be a sample mix-up at the lab too. Can’t tell exactly with just one sample data point. Monitor the coolant level and see if it drops over the next few months.
Customer declined further repairs, just timing belt and components. Surprisingly it ran well, even though timing was way off! They didn't want us to pull the head and check it or anything, but a new belt and all fixed that part
