I have the 6.0 powerstroke and it acts like its vapor locked and it smokes more than normally and I'm also losing water and I can't find a leak what is my problem?

Truthfuly your problem is you bough a ford!! But seriously, your EGR cooler and oil cooler need replacing. Why do I know this! Because I have 20 out of 350 in my fleet and this is happening to everyone of them.
