Fuel injector stuck on so cylinderwere flooded out. When that happens gas goes past the rings draining into the crank. As it is draining into the crank it is also washing the oil off of the cylinder wall so the piston is directly on the cylinder. Metal on metal, no good.
Bowman ran it for me through oasis and it didn't pull anything. I should had kept my 7.3 250 and taught the wife how to drive it.Man sorry to hear that about your truck, I was hoping it was something simple*(because I love Fords and didnt want any more ammo for the haters),so did you run you vin see if there are any open recalls on it?
