Oil on the spark plugs

Hello,

I was changing the spark plugs on my 89 Turbo and i realized that they had oil on the base (the are of the spark plug that ignits the fuel inside the combustion chamber), the first thing i thought was piston o-rings, but i did a compression test and everything was fine.
What can be the cause of this oil on the combustion chamber??

Thanks for the help!
