possible head gaskets?
I would like to pre apologize for my lack of knowledge on how to post on here, this is my forst time. I have a 2006 F350, the truck has an egr delete, new oil cooler and new hpop and upgraded stc. Just recently the truck started to gallop while starting, I was told that a piston had lost compression, according to my scanner it's 3 cylinders, then once the truck starts it smokes a Grey colored smoke like crazy till it hits operating temp. then nothing and it runs perfect until today. I was just heading out on the highway when I heard a pop sound and a massive white cloud behind me, I pulled over to find a quarter size hole in my dog as bottle. Is all this related to head gaskets or is it a couple different issues?
Any help is greatly appreciated!
I should add that the truck still has tons of power and no problem idling, it is a little harder to start then usual but it always does, it always smokes hard for a while after starting tho.

oil level appearing to increase?
creamy color foam I oil system?
if you let truck sit over night...does coolant drain from oil drain plug?
is there oil droplets in coolant tank?
startup is sluggish, or stops, then after a few minutes the engine spins up?
white sweet smelling smoke in exhaust?
coolant level decreasing?
if any of the above, stop driving the vehicle.

The degas cap is designed to relieve pressure, - even pressure from leaking head gaskets. Either your cap did not relieve, or your degas bottle just failed due to bad plastic, or you have a major engine problem that raised the pressure in the degas bottle by so much (and so quickly) that it failed. I think the third possibility is unlikely.
Get a new degas bottle, a new cap, inspect the hoses, and install a pressure gauge on the degas bottle (tie into the vent hose off of the radiator).
Degas bottle F Series...........................................6 C3Z-8A080-B
New degas (coolant overflow) bottle cap.............9C3Z-8101-B
If you need new hoses, we can get you part numbers for them also.

Thanks for the replies so far guys!
I checked the oil again this morning and the level is exactly where it has been for the past month and looks to be of proper viscosity.
I can't check the coolant yet because nothing is open for me to buy anything and there is none left in the degas bottle, there doesn't appear to be any signs of oil residue on the inside of the degas tho. I will buy a new one when Ford opens tomorrow, top it off and fire it up.
When I start the truck the smoke I wouldn't say is sweet more like unburnt diesel and really burns your eyes.
The oil and coolant temps were around 200 for coolant and 204 for oil but they did always move around not usually to much higher than that, always that kind of spread tho.
When turning over it is turning as tho a cylinder or two has no compression like turning normal than really fast for a split sec then slow again and so on... The truck still runs strong and very smooth.

My vote is for cracked injector tip or and injector or 2 that is stuck open. With key off and truck in park/neutral jump the starter wire (passenger side firewall) to the + side of the battery and listen to the motor turn over. Does it still skip or did it suddenly smooth out?
