First off, why are you letting it idle for 1-2 hours?
It is probably a head gasket issue, though they aren't common on the 7.3 PSD unless you are running over 30lbs of boost constantly. Are you getting fuel or oil in the degas bottle also? Head on down to the 99-03 7.3L PSD forum and dig around, there is a ton of really good info and helpful folks.
