Sounds like the gauge isn't connected to the sender. Could be as simple as the cable coming adrift from the sender, or could be a broken cable. I think the cable gets brittle around the sender due to being so close to the manifold.

Oil gauge reading high on open circuit and is not voltage regulated. Everything is built into the instrument pod with the exception of one wire to the sender for gauge and one for light.

If wire breaks to gauge terminal - open circuit reads max.

If sender broke - open circuit reads max.

If oil warning light and gauge wire confused - when pressure reached and light would go off - open circuit reads max and oil light may glow dimly or not.

Can be removed with manifold in place using a cut down spanner - would not recommend to others as will get cut.

When undoing the connections off the top one is a spade and one a ring.

Do not hold sender and undo the terminal nuts. Bakerlite type insulator will usually shatter. Grip the flat sided portions of the threaded pins at the tip and then use a spanner on the nuts.
