Uh-oh oil around spark plug

'88 Toyota Corolla w/4-AF (carbed) engine
The kind of engine where the spark plugs go in on top, in a tube in the center of the head
I just pulled out a spark plug and it was 1/2 covered in oil
The threads and a little bit of the tip were wet but I think that happened unscrewing them
I think there is a half inch or more of oil in the tube
I thought the tube went right to the combustion chamber
I know it needs a head gasket-that's why I started pulling the plugs (see if I should add them to my list-wasn't expecting this)
But the tube doesn't go any where near any gasket
Can those tubes leak?
Any help would be appreciated
Thanks in advance

When you replace the headgasket you will replace the valve cover gasket and the 4 large o-rings around where the plugs go through the valve cover and your problem will be solved.
