    You have blown the head gasket big time.
    I'm surprised you didn't notice that a cylinder was "missing".

    You've got a head gasket that sounds like it's going out. Fuel making it into the cooling jackets is no fun. Not a big deal, take the head off and replace the gasket, flush the cooling system and replace fluids and you should be set. How many miles on the truck? Might replace your injectors while you're in there.

    Yup, head gasket failure. Get em replaced.

    If your engine has lots of hours you might change your valve stem gaskets too. It's cheap and you'll already have the engine open. (A dead give-away of bad valve stem gaskets is, your vehicle sits for awhile and you go to restart it and it puffs some oil out the exhaust.) They are really cheap too, so why not?
