[Proline30]

I have a 2003 f250 4x4 7.3L, 104,442 miles. Never any engine work needed. She has started to blow black smoke from the exhaust when excellerating or stepping into her. Not putting it on the floor just passing someone or something simular.

So far I have checked the air filter, pulled off the large intake to the turbo and checked that. She spins freely and really no movement of the shaft. Whats next to check.

Thanks Tom
