Well, , I didn't check the level after the gasket change so it's possible he made a mistake. The mechanic told me to come back to him after 1000km to to draw the screws again to get the right moment. Then he said it looked good. He noticed a little oil leak from the first part of the exhaust (that is attached to the motor - Sorry for my bad parts discription. It's kind of hard in english). He redrew that bolts too and said that it was ok. I can't see any obvious oil leak either.
