So my neighbor came over and told me my Truck was puffing blue smoke. I started truck and let run about two minutes and moved out of driveway to the road. It sat for about two hours. I started the truck and again let it run a couple minutes before leaving. I turned the truck around and accelerated not to hard but a little bit into it as I pulled away. My neighbor says it puffed blue smoke about 75 yards of so. Being as I'm not to mechanically inclined I'll ask my Trailvoy friends for some advice as to what the issue may be. Still under warranty and has about 38000 miles on it, regular oil changes at 3000. Guess a trip to the dealer may be coming soon.
