So I was doing some routine maintenance on my car. I pulled all the plugs and inspected them, they all looked great. Then I grabbed my endoscope camera, just to see what the cylinders/pistons looked like. Then I found this on cylinder 4. The pictures are terrible, but there is a semicircle directly below the opening for the sparkplug. I am assuming it's the head gasket. Thoughts?
