Good day, there was some oil on the spark plugs, I am going to change the ignition coils to see if that fixes the issue. I will buy an engine valve cover gasket in case that is the issue. I was wondering if the car has spark plug tube seals or do I just change the cover gasket or the coils? Regards

Hello,

Yes, this sounds like it could be a valve cover gasket problem. You might also want to check the volute of your turbo. If your output shaft seal has failed it would leak oil into the volute, compress it, and force feed into your engine, but it would be on all your spark plugs, so yes, back to the valve cover gasket. I have included a link for you to go to down below:
