My corsa e has a trouble with rocker cover gasket. I had oil around the rocker cover gasket. I have taken the car to the dealer and they changed me the rocker cover gasket.
The, after 1 week, I saw that the gasket lose a bit oil around it. (Sorry for my bad english).
They changed me the gasket and the put me liquid silicone. When i take out the oil cap I see that:
They insist when changing the rocker cover gasket loses, it is also put sealant. Is that correct? Must I worry for that?
