The solution is likely.

I had changed the water nozzle and then had not tightened the two cap screws properly enough. This resulted in cooling water in the oil and oil sweating to the outside. Correctly tightened and the leak was eliminated.


You don't need to worry about these few PPMs. Action is only required if a lot of cooling water gets into the oil. You can see that with your eyes. The oil looks like coffee with lots of milk. Critical values ​​start at 5000 mg/l cooling water in the oil.
