Oil found when changing spark plugs

[NocturnalQX4]

So I was changing the plugs and I found oil in the middle plug on the passenger side (sorry I'm not that familiar enough to tell you the cylinder number). When pulling out the coil pack it was soacked in oil. Not sure if I need to change the valve seal or the cylinder needs to be tightened. Any thoughts?

Thanks all

The coils install down through the rocker covers, right? I'd be guessing a rocker cover gasket failure
there. I'd clean up, and reinspect in 100, 1000, and 10,000 miles. The inspection would provide guidance
on whether to bother to fix it.

Agreed, any thoughts on how to change the gasket?
