Now after i got my new sump, checked today and the oil return is leaking! fml does this have a gasket or something on it?

Yes there should be a gasket fitted,you may be alright with some sealant along as you don't put to much on

The little gasket is available through skoda part number 058145757c believe it may be the same as the one that attaches to the turbo on the other end if that pick up pipe... Mine cost £2.30
