Bit of a long shot, but does anyone know what size and style the core plugs are behind the flywheel on the series cars with cast head?? Need to get some sorted before fitting the gearbox and new clutch.
Thought I would reply to my own question in case someone needs to know the answer? Cast head engine which mine is has three 1-1/2" cup type core plugs in the rear of the engine. One behind the flywheel which was the one causing grief on my engine. Now sorted, no more leaks.
