Question type: Maintenance & Repair

Alright so I have this Ford F-250 with the 5.4l v8 and it
starts and runs but it's got bad head gasket or somthing
steams thick white smoke and you can smell antifreeze
exiting the tail pipe.. but I think it's more than just head
gaskets, k so when I first got this truck I knew there was
somthing wrong that's why it was a good deal. I filled the
coolant container "note there's no radiator cap on these
it's just a plastic container with a hose in the bottom going
into radiator" anyway I filled the container just so I could
observe what it was doing started it and ran it I only put
water in no antifreeze, ran engine has little knock that
goes away after it worms up but burns more coolant than
gas. I shut it down now after that it had half emptyd the
coolant container just from driving it in a small circle in a
field and idling for a bit so it sucks water in at a fast rate,
but I walked away for like an hour and looked back under
the hood and the container going into the radiator was
empty no leakage on the ground nothing wet near any
hoses or on the radiator. Is it possible that if the block
could be crackd in a way that the gravity fed design of the
radiator pushed all the water into block? I emptied the oil
out and I filled a 5 gallon pale TO THE BRIM of water
antifreeze and oil sludgy mixture. "The last Engine I saw
this happen to was a chevy vortex 350. 5.7 and it locked
right up sight never turned over again" but this triton 5.4 I
put fresh oil in and it started right up and it was running
with the 5 gallons of sludg. So what do you guys think
cracked block or just really bad head gaskets?
