I got in the truck and started it, there was a funny noise and a loud bang. I shut off the truck and saw smoke coming from under the hood on the passenger side near the windshield. I looked under the hood and decided it needed to go into the shop. I took it to the dealership and was told the spark plug had blown out of the block of the truck, they tried to put it back in but the head had been stripped and the coil was cracked. We were then advised that the truck needed a new head.
