What is the oil leak you are going after?
If it's the rear main, good chance the reason it is leaking is because the main bearings are loose. That could explain the fluttering oil pressure, the crank bouncing up and down at low speeds.
Still, from your readings, that doesn't sound like low enough pressure to turn on the light. Was it thoroughly warmed up? It takes the oil longer to heat up than the coolant and the top end of the engine.
And possibly, not knowing the oiling sequence of the engine, there may be metered oil moving through a open-close port based on rotation of the crank or cam. That is a common method to meter oil to the rocker shaft so not to flood the top with excess oil. If there is a loss of flow resistance beyond the metering device, it could cause a pulsed drop in oil pressure, or that may be the way it is designed. If it is, it would sure be hard on the gauge!
A service manual would be handy to look through, if it can be found.
