I am currently trying to get the 5.3 in my scout started. When I crank the motor oil was pouring out from above the back of the motor, so I looked back there. It appears to be coming from a gaping threaded hole next to the cam shaft position sensor. I looked online and found pictures of the thing that is supposed to be there. Can someone help me out with identifying it? It is that weird plastic thing to the left of the sensor.
