I own a 2012 patriot 2.4L with 117k miles on it and I noticed that I had oil on my engine block on my passenger side of the engine. I tracked the leak back to a sensor that’s underneath/behind the dead center of the exhaust manifold. At first I thought it was a crack in my block. But then I wiped it off and it came right back. My oil is a little low but still in the safe zone I was just wondering if I should take the sensor out and re-seal those threads or do a complete engine rebuild and change my head gasket. Thanks for the help.
