As the title implies I have oil leaking from the rocker shaft acorn nuts. Any ideas for a cure?...Cosmo

There should be a thin flat washer under the acorn nut that helps seal against the rocker box. You might need to replace these washers or you can remove them, apply a very thin bead of sealant, replace the washer and acorn nut. That should do it since the threaded part of the rocker shaft is a fairly snug fit through that side of the rocker box.
