I know with the 5.0 litre vn onwards the oil pick up in the sump is very easily blocked, but i think this would show low oil pressure on the gauge.
The lifters would normally make more noise at idle if they where not holding pressure, not sure of the noise, but could be cracked or broken valve bridges?
