Good evening gentlemen, I think I have a big problem.
I found that my coolant level was going down at least a litre a week.
But no visible leaks at all.

Tonight I did the level again.
I looked at the oil cap word, and there I was very afraid: there was a lot of mayonnaise and also inside.
I’m attaching some pictures.

Yet the car does not overheat. I constantly look at the engine temperature.
And the vehicle does not smoke and behaves properly.

I recently had an oil change (1 month ) and the cap was clean.
I also changed the thermostat and the temperature is now 90°.

What do you think? Did I make a mistake when reassembling the thermostat?
How does the coolant get into the engine oil?

Thanks for your help.
