<< BTW I've seen instances where a dry pump won't even prime the itself.
after several minutes on the starter (without plugs) and still no pressure.
After dropping the pan and geasing up the oilpump the oil pressure built up
quickly, indeed. >>
There are ways around that. Loosten the oil filter or remove the oil pressure
sender/ gauge line. This way the pump isn't pushing against a head.
Completly filling the oil filter with oil makes the condition worse, I add just
oil to the filter to wet the paper.
When building a motor I install the filter, turn the motor upside down, fill
the pump pickup tube then install the pan. After the motor is flipped back
over, over a few qt of oil are added to the pan and the oil pump drive spun.
Using this method I've primed engines by turning a screw driver by hand.
