Tach too, my Punto is standing at the local contract luigi in the workshop with the diagnosis “Cylinder head seal smeared.” I wanted to ask quite stupidly how such a thing comes about? I drive the moustache for 2 years, the last time in the workshop he was in autumn. Should I have checked the cooling fluid, which should not actually dilute itself from a closed system or can it have other reasons? Greeting Desmoda
