Dealer negligent ?

So I decided to do my spark plugs since it was overdue . Come to spark #5 #6 coils have been replaced and there's no record of them replacing it . I had a full print out of my history of my car and no where does it say they did that now there's oil on those spark plug coils I have picture and videos of everything vehicle is now @ 90k miles never raced or abused always well maintained plus and car was verified pre owned and crevice at dealer up until warranty at 75k any feedback would be great thank you for your time

Are you the original owner?

Replacing coils isn't going to cause oil to leak into the plug bore. Nor will improperly tightening the plugs. The valve cover gaskets seal that oil out.

They probably replaced the coils in the process of that diagnostic and just didn't bill them out for whatever reason.
If they initially suspected the coils and replaced them, then found that they were not the cause, they may have chosen to eat the parts rather than try to return used ignition coils to their parts department.

Either way, that won't cause oil to leak into the plug bore. The oil seal (valve cover gaskets) are not disturbed when replacing coils or injectors. Yours are probably just leaking oil. Not a huge deal.
