Thank you guys for all your help. I only drive the truck occasionally and don't have enough down time in my life right now to tear it down right now. I hope you all will bear with me and give me any information I might need when it cooler weather gets here and I have more time. Thanks again.

OK those are a few things I can make time to check now but what is the baro sensor and where is it located and how do I check that and how to check the map. Just a thought but how is it not reasonable to think that the o rings couldn't or wouldn't swell when hot. If I'm wrong in my thinking I just want to understand it better. Thanks

Curious if they are your factory injectors. 220 isn't bad for a set, the highest mileage I have personally seen were 260 ADs with the original orings, they were starting to stick on cold mornings. Others claim they have made well over 300 on a set if properly maintained. Either way, pop your valve covers and see.
In order to change the orings you can address your glow plugs at the same time. Get both from RIFFRAFF DIESEL if you do plan to do so, best prices anywhere. Do all 8!

The O rings don't swell ( they are usually broken to some degree )& the oil thins as it warms up .

I see said the blind man. I see what you saying and I feel with that new knowledge I must agree with you. My original theory on this matter was the hpop because as you said the oil thins out and therefore would be easier to pump (and with that theory I still may be showing my ignorance) it was just a thought. Btw Can any one explain to me the purpose of the exaust back pressure valve on the turbo.

I always thought this was funny considering I have yet to see a 7.3 powered school bus that does not have a deleted pedestal and BV direct from the factory. Curious to what their thought process was on that.... I deleted mine a while back, truck blew as much white with or without it.

I'm one of the few that will never delete or disable the EBP. I deal with much colder temps than most of you do though. I have been in a situation more than once that even with the rad blocked off and EBV closed I had to idle it up to 1800 to maintain any temp at all, and it was only enough to push lukewarm air at that, driving even took a while to get me back to temp. My 00 F250 was the worst of the lot for it, likely thanks to the I/C dropping cylinder temps even more. -40 is a cruel mistress.
School busses up here DID have EBP valves.
