White Smoke, Excessive Moisture, Choppy exhaust flow.

[Lsxtrucker]

Weather here in Florida is in the 70s and 80s range. Exhaust smells like it's running rich, not carburetor rich but it does also have a sweetish scent which would normally point to a coolant leak. Smoke is white, quite noticeable during 15 minutes or so of running and very noticeable at idle. Happens every start regardless of weather/humidity. I understand a certain amount of moisture is normal but my truck is creating a nice sized puddle at the rear tail pipe and another beneath the stock muffler. It sprays my neighbor's vehicle when I rev it up. I notice that while at idle the exhaust doesn't come out in a smooth steady stream you can visually see and feel a choppiness to the exhaust flow almost as if I had a mild aftermarket cam, engine is all stock. Tachometer needle remains steady at idle, no fluctuations. No codes pointing to my catalytic converters. Only code was P0455 which was solved yesterday with a new vent valve solenoid. Truck runs very strong, excellent power. Mileage is 160k.

There is no oil floating in my coolant, no coolant leaks, or coolant /oil consumption. This is what really has me stumped. If it was a head gasket I figure my coolant levels would be dropping or I'd be leaking it somewhere but it stays right on full, zero visible leaks or consumption. 

 

Your help is always appreciated, hope you're all having a nice weekend!

High humidity state, cool nights = heavy condensation
