I changed my spark plugs this weekend and noticed that there was oil around the threads on one of them. Just wanted to know if this is a potential problem?

 

It's not a huge problem but it means you'll need new seals, which also means you'll probably need a new valve cover gasket (unless your's is new), because thats the only way to change the seals. They're just little round rubber pieces that fit in between the head and the valve cover. They're really cheap and it's an easy job. Best of luck to you.

 

Cool, I think I can figure out how to do that. Thanks for the reply.

 

yeah just replace those seals....its really easy and cheap
