3.0 Ford Vulcan in a Mazda B3000. The last Blackstone report came back 164 ppm potassium, 47 ppm silicon. These numbers have had a steady increase over the past couple of years. Iron came back at 9, copper 0, lead 2.
Note from Blackstone: “unfortunately, potassium and sodium increased again. These levels still don’t show much coolant contamination, but they do show more that there was in previous samples. It still doesn’t look like the coolant is causing much (if any) trouble for the engine’s wearing parts. Suggest sticking with 2,500 mile oil changes to monitor the coolant situation.”
The truck has 96k, Oil Supertech 5w-30. Runs great, no signs of any other issues. Is this a sign of the timing cover case leaking coolant into the oil? Does this level of potassium and silicon warrant a taking apart the water pump/timing chain/timing cover to see what is going on? I am not a fan of any type of stop leak in the cooling system. And I do not have much experience with these Ford Vulcan engines. Google search seems to indicate that some of these have this type of issue.
Do I have someone take it apart for a look see?
Do I keep running 2.5/3k oil changes and monitor through analysis?
Do I just run it until it has an obvious issue?
A new truck is not an option, I would like to keep this for years as a winter vehicle, and work around the yard type truck. Not used for towing. A small pop us is not out of the question at some point. It does get loaded up with camping gear a few times a year, and taken on around New England.
Not sure to post this on Used Oil Analysis or Mechanical. Feel free to move it if not correct.
