Oil Leak

Hi All,

I'm new here and hoping I can get some help. I have a 2005 XC90 2.5t with 110k on it. When changing the spark plugs, I noticed oil on the top of what I believe to be the last or #5 plug. All others were clean. I can also smell oil burning when I get in the car if it's been running. It burns a quart every 1k. It's getting pretty annoying.

Any ides as to what this can be? Also, any links to how to fix the problem? I'm fairly handy with cars, but need some guidance on how to complete a repair of this nature.

Thanks for your help!

I will wipe off the oil clean.
Replace the oil filler cap gasket/o'ring, and keep an eye on it.
What is the mileage?

100000 miles is reasonable to explore PCV, this post will offer next steps https://www.matthewsvolvosite.com/forums/viewtopic.php?f=1&t=28334&start=14
