So my sister was coming back from Oklahoma pulling her horse trailer and her truck (blew up) he words not mine it has these codes (there point to #8). She said it started poring black/grey smoke and running very rough. They say coolant is in good. Said there is power steering or Trans fluid everywhere. Haven’t got confirmation on witch yet. I have her some starting it and pulling the oil cap off to see what he sees. He’s doing this tomorrow. Dose this sound like what they do when the crack a piston?
