Do you have access to a live time scanner? I have to be honest, moisture is normal from the exhaust. White smoke isn't. It sounds like coolant, but maybe there is an issue with something like the coolant temp sensor. If it tells the computer the temp is colder than it is, the computer will dump fuel to compensate. There also could be a leaking fuel injector. Have you checked fuel pump pressure to make sure the regulator is doing its job?
Since it is using so much fuel, I am questioning if it is running too rich. I have to be honest, a rich mixture usually causes black smoke from the exhaust.
NOTE: I am assuming that all the original sensors have been installed in the same locations on the new engine.
