The problem is most likely a failed head gasket or perhaps a cracked cylinder head casting. Try applying pressure to the cooling system overnight and see if it pushes water into the combustion chambers, of course you will need to remove all the spark plugs to avoid doing damage to the engine when it is turned over.

the cooling system was completely vacum down to have no air in system the car turns over and runs when car turns off, the tail pipes still smoke little bit . If the car had vacum leak from main head gasket would that lead the engine to run normal in idle and less under load of driving?I did pull off the spark plugs and there is oil on every single one of them no water contaminent was seen on the tip of the plug and I used one of those guides you find in those generic repair manuals to see it just oil on the plugs? could the head gasket lead to that type of failure or could the oil be coming from some were else?

How long did the motor run and how much smoke/steam was coming out? Was it just condensation, did the motor come all the way up to operating temperature?
