If your sure its oil and not gasoline on them, It could be several things letting oil into the cylinder. A more common thing is valve stem seals going bad and letting oil down by the valve into the cylinder. Does the car burn oil and smoke alot? What is the makemodelyear etc.. of your car? If it does smoke does it get worse as it warms up ?

Other than you finding oil on the spark plugs, how does the car run? How does it act? Could be an oil seal somewhere.. the valve cover gasket isnt the only one that could cause that, there are several seals in the head. Are you for sure its oil on the plug?

[samuel]

yes im sure i remove them and the car run like new no misfire

Sounds like its just a seal problem. Im not an expert on hyundai heads so you would have to find out what all seals it has, but likely its a seal that goes right where the plug goes into the head considering you replaced the valve cover gasket, and you said you found oil on both sides of the plug. Or less likely it could be the seal that goes on top of the inside of the valve cover that keeps oil out of the tube that your ignition coil slides into. But im not an expert on overhead cam engines. Just telling you what i know.

thanks you 😉

Do the spark plugs reside inside the valve cover? If so, did you change the tube seals? Further more did you install them in the correct direction?
