hey so i was taking my spark plugs apart and saw that i had oil in my first spark plug like once i take out the spark plug wire and was wondering what that was and how to fix it if anyone out there knows that would be great and if thats bad for my motor thanks

 

Most likely your valve cover spark plug tube seals..

And oil in your cylinder/ on your plug can foul out your plug.

Your gonna need to pull the valve cover off.. replace the gaskets and the valve cover gasket and put a new plug in.

 

i replaced the seals on my ls and continued to get that problem...found out that i had a broken valve cover bolt and the seal wasn't sealing correctly. i suggest you go buy the seal kit from autozone/napa/etc. and just make sure all your bolts are on the valve cover
