My friend said his truck was missing hard. White smoke while driving. He towed it to my house. It’s a 2002 f250 4x4. About 220k miles on it. I confirmed the rough idle. Ran code and got an IDM code. Buzz tested and got a P1275. Cylinder 5 buzzed super low on sound. I looked at wiring pigtail to uvch and nothing noticeable. Then moved the 2 heater hoses aside and saw smoke existing a hole in the valve cover. Please see images. What could this be? Should I go ahead and pull the valve cover? Is there something I should be careful when doing this. Anybody seen something like this?
Above cylinder 5 Smoke was exiting this hole. punctured from under valve cover. I can feel something pushing through
Pull the valve cover. Miss from a valvetrain part or glow plug spitting out through the valve cover causing lack of compression and raw fuel out the exhaust.
Pulled valve cover. Looks like glow plug shot out. The harness plug to injector is loose as well as glow plug power plug. I see the treads from glow plug. How does this happen?
What should next steps be? First time with glow plugs. Do I need to just replace the plug assuming that the old one is fully intact.
I’m guessing fuel got into valve cover area and I see pooling around other glow plugs. Do I vacuum out all pooling of visible fuel? What should I be aware of with this glow plug that shot out?
You're going to need a new UVCH because that one is all torn up and pull the GP out and see what it looks like. Hope it all comes out in one piece because if there's any left behind, you might need to pull the head. What you do with your oil is up to you and how much fuel you think you got into the crankcase. Changing it will remove all doubt. I don't know if there are bore scopes small enough to fit through that GP hole but if there are, I'd take a peek. Let's see what others have to say about it all.

see image of gp I got out. Looks to be complete and bent!
The glow plug reads autolite.
I have UVCH, new passenger gasket and new pig tail for exterior plug (if needed).
need to get oem glow plugs. Need new valve cover due to damage.
hoping the treads in head for glow plug aren’t damaged. With a flashlight I don’t see the damage to them. I do see where the gp thrusted up and rubbed the solenoid and where the uvch harness plugs into it. They seem to be ok and not loose or cracked.
Were the glow plugs replaced previously? If so I'd check and tighten all of them to spec. If not might want to test and possibly replace them all. With the cover off I'd at the least check the torque on everything especially if any previous work has been done. The changing of the oil would seem to be required.

plan is to change all 4 glow plugs on this passenger side right now. Hopefully there was not any other damage. What is the torque on the glow plugs? Should I check torque on anything else while in there? If so, can you provide a list or link that may guide me on this procedure?
looking to get it all back together and test it out.
thanks everyone for the support and shared knowledge.
Take them ALL out and replace with Motorcraft ZD-30s. The next mechanic to work on it will appreciate not having to sweat bullets worrying about head removal when the tip breaks off and gets stuck.
Or maybe don't.....you don't want to be the guy who breaks one off!

Be careful about where you buy them from. SkySkiJason did a write up on counterfeits that are hard (but not impossible) to distinguish from real ones and counterfeits seem to be plentiful on fleaby and maybe amazoo. But from Ford, RiffRaff or other reputable seller. Whatever bent that glow plug needs to be determined and addressed, if you ask me. I doubt that compression alone pushed that out of there.
