Tea leaf reading anyone- how about these spark plugs ?
I removed what I think are the original plugs today (37K miles on a 2002 XJ8) and I found a small amount of oil on the threads of 2 of the plugs. As I peered wayyyyy down into the head I could see just a few drops of fresh clean oil.
I'm assuming this means that there is a small valve cover gasket leak...yes?
The plugs I removed were NGK [U]R [U] PFR50 11E and were gapped at .040 Are these likely factory originals??
I replaced them with NGK Iridium IX BKREIX-11 stock # 5464 gapped to .035, drove the car to test and it ran flawlessly, so I didn't mess anything up
I'm attaching a photo of the plugs-what do these tell you?
Thank you in advance for all your help

I thought I would change the plugs since the plugs were in the car 10 years. I was also curious to find out if they would be easy to remove, which they were.
So I should be able to go 100K miles on this set of iridium plugs then?
