Driving the truck today and started to hear what sounded like and exhaust leak on the driver side manifold or uppipe. Went to an event called tha kshiving burnouts and started to do one. White smoke started pouring out from around the hood(smoke smelled like burning oil). Checked under the hood and it smells like fuel. Also. All injector balance rates were near zero except cyl 8 said 3.1. Any ideas?
