THIS IS A POSSIBILITY but it could be the one of the brass freeze plugs that started leaking OR the intake manifold gasket which also has a coolent passage running through could be leaking

IM gasket, freeze plug, cursed water plug, or the heater core outlet to block gasket.

Although not Miata, but very informative in regards to overheating:

Coolant leaks dont go away by magic.

have any of your radiator hose popped off yet?
oil in water
and water in oil is never a good sign.

as in have the hoses come off?

if you are looking at head gasket, the compression from the cylinder will go into the cooling system (~150-200psi)

yeah, popped off.
came off.
reason i ask is cause i've had two cars with head gasket issues.
when the head gasket is poor, the pressure inside the system becomes greater.
on both cars, my upper radiator hose popped off while driving and spilled coolant everywhere.
