im betting you just have blown head gaskets. im more than certain you have at least that. there are plenty of threads with 4.7s having the same issue. as for number one being wet, again, could just be mainly coolant.

normally with a straigh coolent leak like that it will clean a plug and your throwing the same code both time that p0201. honestly im thinking that it has either a bad injector or Pcm. the injector is shorting out and sticking open and the fuel pump is pumping 50 lbs of fuel in the cylinder. the only other way to know whis for sure is to unplug the injector and see if it clears up (except for skipping). also i would be pulling the dip stick and smelling the oil and see if it smells like gas. in all theory by the time you get the motor cool and plugs out that gas should have bypassed the rings and entered the base allowing for the plug to just look wet and not flowing the cylinder like it would when the fuel pump is running. i agree that the white smoke it condinsation. mine has done it for years and i have good heads and cat

@ atthewmartin114 - a little white smoke when you first crank up and start is normal. Im talking about a different level of white smoke

@ everyone else - Look at your exhaust under the truck and see how the cats could hold liquid in the bottom of them as the are bigger in diameter than the exh pipes and mounted center to center. Look at the muffler also. If you are getting raw liquid fuel pumped out the block and into the exh, think about the temperature of the exh and how hot it heats the metal exh pipes. Then think about how anything flammable reacts when ignited in a restricted or confined space. See where Im going with this?

I would say a blown head gasket and when you are running the engine the gas is mixing with the coolant and going out your exhaust.

ok i understand your boom theory but do me a favor. go out to your bike(providing you have one) crank the forward carb jet wide open and fire the bike up lit it idle for ten minutes or so then take the temp of the exhaust pipe. i bet theres several hundred degrees differance.

what im saying is that is his right bank has an injector that it no stuck wide open and he is pumping 60 psi of fuel in to the block out the manifold and into the y pipe its going to act like a plummer trying to heat a pipe with water in it. its dispersing the heat. so the fuel doesnt actually ingite. ( this can be tested with any coffee can poor gas in the bottom. grab your buddys light cig and drop it into the liquid it will not blow up i promase) so yea if it started randomly at 50 after the truck ran for days i would expect some kind of explotion or burning or something.

- i would be draining the oil and pulling the fuel rail and injectors up and replacing them or figuring out which cylinder is leaking down and replacing that one. also most of these truck will admit a blueish smoke under morning start up and will then disipate to white which is caused by the CAT changing the co2 in the h2o. the only issue i have with this whole theory is that my truck doesnt have a cat in it and i still get the light white smoke and the water out of the exhaust.
