do I need injectors or just o-rings

I'm working on a 1999 F450 with 7.3.
The truck has no power & has a misfire when I accelerate.
I removed the valve covers to inspect the injector situation.
A couple have very little oil coming out of them.
How do I know if I need injectors or just new orings?
At 300 each I don't want to replace the injectors if I don't have to.
On another note this truck dose not smoke allmost at all. even when its cold there's about as much exost as a car. My other powerstrokes have all smoked a lot more but this is newer. I never see the ebpv move could it be stuck?

There are a lot of other things that could cause those issues.
Have you ruled out ICP/IPR related by use of a scanner?
Perhaps a short in the UVCH?
Turbo building boost like it should?

is it consuming oil? Check the fuelbowl filter for oil contamination.

I think you may be on the right track with the ICP or IPR. The conector on the IPR seems loose I removed it & cleaned it & put it back. I removed the wire from the ICP (I saw a utube vid that said if the ICP is bad it will start & run fine when you remove the wire because it dose not get the signal to open the IPR dumping the oil.) & it seems much better. no more mis. I tested the injectors with it running by removing the wires one at a time. They all made the motor slow bown so they are all doing ok at least at idle but it didn't mis at idle.
I checked the fuel bowl & no signs of oil in the fuel. I don't think it burns oil, it dosen't smoke at all I think it's strange how little it smokes. I don't know what the UVCH is?
I'm going to go buy a new sensor.

Thanks for all the help. I like working through these things so I know where to look the next time.
I bought this truck not running & between here & utube I've worked through most of the problems. It's nice to see it comming back to life.

I put in the new Fuel Injector presure sensor. It has a lot of power back but still misses. not as bad mostly going up hill or when I step on it
I put in a new crank sosition sensor. that took care of the misfires.
260xxx miles & she runs like a champ now.
I got it for 800 not running
filters & oil 100.00
Glow plug relay was stoping it from starting 60.00
fuel injector presure sensor caused low power 170.00
Crank position sensor caused misfire 30.00
With some paper towles & brake cleaner oh & some seafoam I have 1200 in it Not bad for a weekend of work

Thanks Joel & timmyboy for your help. Oh & Utube theres some great videos on there if you want to see what to expect when you take stuff apart.
