silverwrx19224 Scooby Newbie Member#: 500246 Join Date: Apr 2019 Location: MD Vehicle: 17 WRX Silver	One brown oily spark plug I changed the spark plugs in my 2017 WRX that has 44K miles on it this weekend and noticed one plug had some oil build up and looked like there are some issues. Ive added images below. But, is this due to a gasket leak or should I look into something else? The car runs fine and has no loss of power. The order of the plugs is the same as orientation as they were pulled from the engine.
