Hi,

It isn't uncommon for oil to be around a spark plug. What happens most times is a leak from the valve cover which allows a small amount of oil to leak past the gasket into the spark plug well. As long and there wasn't a puddle of oil, it's not a big concern.

As far as the spark plugs, here is a link you may find helpful when replacing them:

The attachments below are the directions specific to your vehicle for replacement.

I hope this helps. Let me know if you have other questions.

Take care,

Joe
