So I am about to track down an oil leak on my 7.3 I am sure its on top and leaking down into the valley. I know its leaking down the backside of the motor. What are some of the common locations for leaks I can start looking at? I dont know much about the 7.3 so any pics would be helpful. I need to get this fixed since its starting to blow up the back side of the tailgate and spotting on the bed. It looks really bad.
