Turbo oil feed oil weep

[S3 Dave]

Hi I'm getting a really small amount of oil leaking from the oil feed to the turbo. It appears to be wet when you look up at the Allen screws where the hoses fit. Is this fairly easy to cure I'm guessing there will be a gasket involved??

I've got it down to the return line gasket on the turbo. Anyone know how hard it is to change?? Only a few quid for the gasket!
