05 f250 in losing coolant its starting to get worse.
start up white smoke is also getting more and staying around longer. i looked and only wet i see is behind egr. also under motor. signs of my resvoir puking with white resdue on my hood and aroubs coolant cap.
The coolant behind the EGR in the valley can come from either the Intake-to-EGR o-ring, the gasket on the cover of the (where the blue hose enters the oil cooler housing) or the o-ring underneath it that seals its surface with the oil cooler up pipe, the big doughnut under the intake manifold, the small hose running from the degas bottle to the intake manifold, or that blue tube itself. From your pic, I wouldn't guess the doughnut. It appears that someone has replaced that blue tube before and used straight tube with screw clamps rather than the OEM twist-connect tube. I can't tell if they used the recommended "???" (I forget, maybe silicone) hose or went with cheaper heater hose. The OEM part is about $50.
It doesn't look like that coolant is coming out of the degas cap. When it does that, it's usually pretty obvious all around the cap itself and right underneath it. The residue in the pics looks like one of the small degas hoses is leaking, or maybe it's squirting up from a leak at the manifold end of that small hose - a leak there could maybe cause both the wetness in both areas.
You might borrow the pump tester from AutoZone, although the one I got I couldn't get the degas bottle adapter to see up, so it was useless. If it has a good adapter, you can hand pump your system up to 15lbs and see it coolant squirts out somewhere.
That said, your degas bottle is looking pretty black inside - is there oil in the coolant?

i just replaced the cap a month ago hoping that was it.
would i be able to just open the hood when the truck is up to temp to see?
i have only had this truck for 2 months now. so that stuff you mentioned that was replaced i honestly dont know if its better quality or not.
the deegas seems dirty. but i drained the coolant out when i replaced the exghuast pressure sensor. did not see any coolant in it. i replaced that a week or two ago.
i know its still holding pressure

I'm hoping some other guys will chime in - I don't have a lot of experience with coolant spraying around the engine, although I've seen many pics, and you're not giving us any info. You say you've only had the truck a short time - do you know much about diesels, or this engine specifically? Do you have a data/code reader to monitor what the engine is doing? You gotta have one - it's literally foolish and naive to drive one of these trucks without being able to monitor data. Is the truck loosing coolant. What is the coolant temp while driving? Does it have an even crank (indication of good compression on all cylinders), or can you hear a thunk each time the engine cycles (a bad cylinder)? (Crank the engine with the starter wire under the hood with the ignition key off to listen to the engine).
I'm trying to lead your through the preliminary steps to determine whether an overheating, over pressurized engine/coolant system is forcing coolant out, or if you just have a coolant leak from a bad o-ring, clamp, or gasket. My guess is you just have a leak. The engine overheat/over pressurize scenario typically happens when you have blown head gaskets, but the first place coolant is forced out is the degas cap - that's kinda what it's made to do. Your EGR cooler is deleted, so it can't be the problem. Maybe your thermostat is stuck closed and causing your truck to overheat. Your oil cooler may be leaking - although that's often caused by a blown EGR cooler which you don't have. Could be that someone yanked the EGR cooler but not before it had messed up the oil cooler, or the oil cooler is just old and due for a change. Still, that doesn't cause coolant to spew, I don't think. It might cause head gaskets to blow, which spews coolant, but again, out the cap first.
You need data - coolant temp, oil temps, coolant pressure, fault codes. You need to know whether you're losing coolant, and how much. You need to watch your coolant temp to see if/when the thermostat is opening. You need to raise your coolant pressure to operating temp, release it, and drive some more to see what it does.

no i dont know a crazy a lot about diesels. only from work and driving internationals and macks. Which isnt tbe best since they just bandage the trucks till next time.
i use forscan
the coolant seems to be running at normal temp from what i can see.
the truck starts normally for me and runs fine.
this was probably only 20 minutes of driving the data i posted
when i stopped at speedway i opened the hood this morning and saw that around the cap.
as far as the 10mm thats been there i assume since i drove her home
replaced cap wheb got home. took the truck for a drive on start up white smoke. decent amount id say. after awhile went away. drove it around to get it up to temp. opened the hood. noticed still doing it but the hose on the left was wet around the connection to degas bottle. also went underneath. other connections off the deegas bottle was dry. just also around the cap was wet.
started the truck up no white smoke while hot.
so head gasket?
That looks more like oil around the bottom of the cap. Degas bottle looks awfully dark too. If it is oil, you've got a blown oil cooler or blown head gaskets. Almost impossible to tell which without pulling the oil cooler. That's where the history of the truck comes into play.

its not oil. i can drain the coolant and show you guys. it doesnt come out dark. also my oil is still full and doesnt look like its mixing with anything
when i took that picture i did notice i have bubbling in my coolant degas bottle also
With the amount of coolant shown in your pics without towing or stressing the engine, and the bubbling at idle.....you may have blown head gaskets.
Search around the forum, and "tee" in a pressure gauge to see what kind of pressure you're pumping into the cooling system. Sounds like your main issue is combustion leaking into the coolant system.
You could also go buy a kit to determine this as well.

Good Luck
i assume its more then likely to be my head gasket. the motor isnt studded so ill be doing the bulletproofing. i honestly was hoping for egr.
but with my luck i doubt it
It looks like the EGR cooler is missing. Possibly a previous owner did an EGR cooler delete? If so, then that's not your problem. Either one of your coolant related hoses is leaking. Or you have a combustion leak. But, before panicking, lets check your coolant pressure and test the cooling system to check for leaks. B.
