Does anybody know of the (normal) existence of a gasket ring fitted under the gearbox filler G104? When i removed mine one was fitted under there- and i doubt it had ever been removed before.I cannot find any reference to a gasket here, and i wonder if anyone else has found similar- its a simple gasket paper washer, quite thick, say 1-1.5mm (which would affect dipstick reading a tiny bit I suppose) Did Vincents fit them from new but never let on, or is mine an addition? Cheers, bob.
