We have been building Big HP RB30'S for years & have always been looking at ways to improve the oil system & this includes oil getting back to the sump, well it took us long enough & here it is the only RB you can not find a cylinder head drain for until now.
Our drain comes with instructions to fit & is made of T6 billet designed & manufactured in house. The fitting replaces the rear cam plug & will increase the oil return & flow back to the sump.
