Oil in spark plug hole

Today when I changed my oil, I decided to pull a spark plug boot on the passenger side of the engine. When I pulled it, I was shocked to see oil on the part of the boot that goes into the spark plug hole, as well as pooled oil inside the spark plug hole.

What causes this???

Car runs fine - no CELs...

Stumped!

Thanks for any and all replies.

It sounds like you need to replace the spark plug tube seal(s).

There are grommets/seals that go where the plug holes are, they can leak and result in this issue. You'll need to pull the valve cover off and replace all the gaskets. Its not terribly hard to do. If you can change the plugs, you can probably do this.

Thanks to all for the replies - guess I have to pencil in a day to do the repair. Of course they had to wait until WINTER to start leaking (I have an unheated garage)

Seals love to leak in the winter. They shrink up to there smallest size. If it's not misfiring you could wait till it warms up.
