After feeling vibrations while driving, I decided to check the spark plugs on my Maxima. It turned out that one of the plugs was covered in engine oil. I brought it to a mechanic and he said that mostly likely it's the piston ring that needs to be replaced. The job would cost around $1,500 because it will involve a lot of labor hours. He also said that I can keep on driving it until it quits. Any suggestions?

 

I'd say get a second opinion. I can tell you that on previous cars I have owned I had oil on the spark plug and it turned out to be a valve cover gasket. I mean the guy could be right, but why not get another opinion and see what they have to say.

 

Umm refrain from 2x posting the same thing.
