Hello I just bought a 1996 f350 7.3 powertroke and it runs great no problems it has a ts6 chip cold air intake and 4 inch exhaust and I just noticed light blue smoke once it starts up but goes away once warmed up and I'm curious what it is and should I be worried and is it a serious problem or can I drive it for alittle while still thank you for the help any thing would be appreciated

Yep. Check glow plug system.
How long does the smoke last?
If it's only a few seconds, that's usually glow plugs. But if it takes awhile, that can be bad injectors.

Sounds pretty normal to me. If the cat has been removed, they'll smoke a little when cold. I'll 3rd or 4th checking the glowplugs, though.
