If the oil is on the inside parts of the spark plug like the bottom insulator, that's a bigger issue, you have either leaking valve seals or very leaky piston rings. If your car blows a puff of blue smoke on startup, you probably ave leaky valve seals. If it blows blue smoke all the time, leaky piston rings.
B) if the oil is not leaking/spraying into your engine compartment, which will seriously shorten the life of any hoses, gaskets, seals, etc. it gets on, and might cause whole new problems. Only drive with a leak if you have to, but book a service call now.
