Vespa gts 250, 2013 model. 35000 km. You made a bit of a mess when you changed the oil last year. The mechanic connected the housing and the artificial with a liquid gasket. I waited 2 days and miracle. I have been using it for 1 year. But now I need to change the oil. Should I seal it again with a liquid seal or they suggested a helicoil spring? Do you think Helicoil would be safer? First, it opens the slot, then it adds oil and the oil plug goes into the spring. I write with Google Translate. Sorry🙏
