Yes, not of the Nissonger problem but I was aware the cable core was
designed to throw oil back into the box. I thought it was the twist in the
inner cable rather than the weave of an outer cover.
Cable driven Tachographs on goods vehicles suffer from a similar aftermarket
problems and is one of the faults you were taught to detect.
