It just needs injectors and a tappet cover gasket. Guy was a "6.5 god" according to him. He said it had cracked rings or a dropped valve because it was blowing back out of the intake...... I got there and he showed me what he was talking about and I just kind of nodded my head and loaded it up. His blowing out of the intake was air coming out of the front of the tappet cover gasket because it's hard as a rock and cracked lol. Fires right up and runs fine I drove it but smokes a little white when running like the pop off pressure is low on them. It is missing the turbo now and the fan but that's it. I'll guarantee the motor is good and no major issues for having 300k on it if it's original.
