Are you sure it is coming from the stud.It is usually from a leak further up, either from the oil filter housing flange or the even higher up the oil pressure switch or the distributor seal.

yeah can see it weeping when running and everything else has been changed oil cooler seals oil filter housing gasket rear main seal distributor seal all done

I think you know the answer - bolt needs to come out and be resealed. You should be able to do that with no detriment. A copper washer might be sufficient to stop it weeping. Probably need to drain the oil though.
