Hey everyone, I had created a thread previously about oil on my spark plug but can’t seem to fix it. My second cylinder kept having a misfire, so I had changed my tube seals, my valve cover seals, my pcv valve, as well as all spark plugs and one ignition coil. After a couple weeks my second cylinder started to misfire again. When I pull out the spark plug there is oil on the threading of the plugging and a small amount where the plug seats to the tube seal. It’ll drive well for about 2 weeks until the oil just burns out my spark plug. After this work I had done I brought it to a friend who cleaned it all out and ran a compression test. My compression is good and holds. I was thinking it could be my piston ring that is gone or possibly my whole head might have a small crack somewhere.. anyone have any insight or speculations? Any and all answers will be greatly appreciated. Thank you everyone. It is a 2013 Dodge Dart 1.4L with 96,000kms.
