The vac line will only be a problem with the climate control and the auto hubs. The climate control will default to defrost and the front hubs will not engage or disengage without vacuum. Think of them like a ball point pen, one shot of vac and off will turn them on and to release another shot of vac and they will release.

Your pics are of the vacuum pump and the heater bypass valve. Loosing vacuum shouldn't cause any issues to your engine running, it would just default the vents to defrost and cause issues with the vacuum hub autolocks if you are 4WD.

when I did the check on the FICM I got
47.7 at key on and then I got 47.8 while cranking and while the motor was running. Is it safe to say the FICM is ok so that I can concentrate on something different like the EGR and cooler.

I changed out the EGR valve and drove it around, it really didn't smoke as much but it did smoke some after warming up. What about the ICP and pigtail?

I have an 04 f250 with the 6.0 and have about 191,000 miles. The last couple of days I have noticed alot of white smoke and at times black smoke. Also seems like lack of power off the line. Could it be bad injectors ( I have never replaced them since ive owned the truck at
50,000 miles.) No major repairs have had to be done to the truck yet. Im sure it is about to catch up with me though. I did resolder the point on the FICM, could that be the issue again?

the ICP ( Injection control pressure ) if oil is out the back side ( connection side) would mean bad sensor you could monitor ICP and ICPV (volts) those two are a little more prone to stall buck surge, and low pressure

pulled the connector off the ICP and there is no oil anywhere, so I'm assuming the ICP is ok. So now on to the turbo downpipe, if there is oil then I need to get a oil seal kit. Also I pulled the EBP tube and it was clear.

I took the down pipe off at the cat and it was dry inside, except for a little soot. I couldn't take it off at the turbo due to a I metal piece that was holding the two together at he turbo.
