Is is best to assume that when a coil is (has) leaked oil that is is no good to use? I noticed it on one of my stored cars. Not ready to start the car for the year and now is the time I can just swap out the coil if it will be no good.
 
Yes, chunk it. The oil is what keeps the coil cool and that one will fail, probably at the most inopportune time. Murphy's Law.
 
Had a car that experienced a no start under damp conditions. Kept changing plugs, wires and cap to no avail. Noticed bottom of coil oily, changed that and no problem after that.
 
It depends on the design of the coil. Model A coils were upside down when compared to the 8BA era vehicles.
 
I don't know if they're still selling cast epoxy coils, but I am still using one (6-volt) on my '55 and it has got to be about 35 years old now. Oh, you won't see it offered by any of the repro parts suppliers. Maybe could special order one out of Napa, but back then, the cast epoxy coil was a standard replacement for OEM oil filled coils.
