> the valve gear was necessary, I would have ensured a direct pressure feed
> from the pump. The only two ways the existing supply can suffer is from
> partially or fully sludge blocked oil ways within the valve gear itself, or
> worn grooves on the back end of the camshaft. If the pump is working as it
> should and the camshaft in good condition, then the internal supply will be
> more than sufficient. A reliable check is to leave the engine idling for no
> more than five minutes with the rocker cover removed. If flecks of oil are
> found on the surrounding panelwork, the oil supply is performing as it
> should, as designed and needs no further intervention."
> "May I quote you on that?"
> "By all means. Please convey to your friends that my four and six cylinder
> engines do not need an additional oil supply of the type you suggest. In
