Oil in spark plug chamber

[Bala]

The three coils that I looked were good. But will take a closer look when replacing the tubes. They had some oil and dirt on them. I will replace all the tubes and and sockets for the sake of piece of mind. They seem inexpensive anyway.

So, I remove the spark plug, pull out the tube with pliers, apply engine oil to the new one and put it in with the o rings? Seems pretty simple.

Thanks guys!
