Oil in the spark plugs

I've got a 2005 Megane grand scenic and have the emissions warning coming on. The car isn't running smoothly either.
I've changed the ignition coils and thought they had worked because the warning went and it drove smooth again.
But it has now come back and isn't driving smooth.
Could it be to do with the fact 2 of the 4 coils had oil on them?
If so, what could be causing this?
Looks like there is oil on the top near to the entrances to them coils as well.
Where could it be coming from and can I fix it?
Thanks
