Do I need new injectors?

[Pwnm30rdi3]

I have had the truck for 6,500 miles. It's a Early 1999 F250 7.3 6 speed manual.
The more I have to fix on this truck the more I realize that the owner before me half assed everything.

The truck has 315,000 miles on it.

Every time I start the truck it white smokes until it's warmed up.
When its warm out it smokes less, when its cold out it smokes more.
I just replaced all the glow plugs and the glow plug relay 2-3 months ago.

Heres a video of the truck being started in 76-80 degree weather.

I think you might have the same problem I am dealing with right now. while the truck is running take the oil fill cap off and see how much white smoke is coming from that, then place the cap upside down and see if it blows off. if it blows off you need rings if not you might need new injector seats to fix your current white smoke problem from the exhaust.

They told me my Injector O-Rings were bad and that I might be needing injectors soon.

Looks like I will be buying an O-ring set from riffraff!
