Never come across that one, having said that i'm not entierely sure what actually lubricates the internal bearings in the dizzy.
....it makes more sense with pictures!!!
RV8 factory overhaul manual said:
The full flow lubrication system uses a gear type oil pump driven from the crankshaft. The assembly is integral with the timing cover which also carries the full flow oil filter, oil pressure switch and pressure relief valve.
Oil is drawn from the pressed steel sump through a strainer and into the oil pump, excess pressure being relieved by the pressure relief valve. The oil pressure warning light switch is screwed into the oil pump cover and registers the oil pressure in the main oil gallery on the outflow side of the filter.
Pressurised oil passes through an oil cooler, if fitted, to the full flow oil filter and to internal drillings in the crankshaft where it is directed to each main bearing and to the big end bearings via Nos. 1, 3 and 5 main bearings. An internal drilling in the cylinder block directs oil to the camshaft where it passes through further internal drillings to the hydraulic tappets, camshaft journals and rocker shaft. Lubrication to the thrust side of the cylinders is by oil grooves
machined in each connecting rod big end joint face, which are timed to align with holes in the big end journals on the power and exhaust strokes.
The distributor drive and timing chain are lubricated from the camshaft front bearing. The feed to the timing chain is channelled along the camshaft sprocket, key and spacer.
