Help - 216 no oil pressure!

[Lynn Eades]

Harry, As Grant has stated, about the dizzy.
When you drop in the dizzy, the gear on the bottom meshes with the cam shaft, but the dog teeth on the bottom don't always line up with the pump slot. You have to turn the pump with a screw driver to line up with the dog, which doesn't happen easily, because the gear on the dizzy turns going in. It might take a few goes to get it in.
You shouldn't need a drill to turn the pump as it will only take a couple of turns of a suitable screwdriver to feel the resistance of the oil pressure(you had pressure before?)when you turn the pump in the correct direction.
Your oil pressure to the valve gear is only low pressure, and low volume. It is fed from a cam bearing and regulated by machined cuts in the camshaft, so this is not the reason for the sudden loss of all your oil pressure.
Good luck!
