Ford Scorpio 2.3 Tournament/Cylinder Head Seal???

Hello, I bought a 97 Ford Scorpio 2.3 tournament Ghia automatic on the weekend. The car ran 204.000 KM and the engine runs super quiet and clean, transmission switches clean, everything wonderful! We are not driving much more, much short distance, but space for children and prams had to be already, therefore the ship, which was also super cheap in somewhat maintenance condition. Now I noticed that the compensation tank for the cooling water empties very quickly, a I have not been able to see that the oil level is not too high. Has anyone had an idea or experience? Could it be the cylinder head gasket? But then the water would get into the oil cycle and the oil would be watery and the oil level too high or not? Both not the case! Please ask for your tips, thank you! Oh yes, and if someone has experience how expensive the fun (in the free screwdriver) is, I am grateful for your answers! Many greetings from Dortmund
