Hi has anyone had this problem ? 2006 magnum sxt 3.5, 115,000 miles. Low gas mileage, seems to use a lot of oil. Removed pluem and noticed oil on intake. Car seems to have lost some of its power. Also the plugs seemed to have a yellow ring on them. I'm I looking at a new engine?

 

When is the last time you changed your PCV valve?

 

I have not changed it , will do it today, any other ideas?

 

Possibly oil getting past the outside of a valve guide. I have seen NUMEROUS issues with the late model 3.5 heads. Specifically the valves and guides. Any misfire codes?
