Oh I saw your pics.
That's basically a dust seal plugging where a mechanical fuel pump would go with the earlier fuel system. It's basically a stainless freeze plug from Napa.
It's odd that it popped out. You may have some blow by developing, or it could have just vibrated up and out.
A new freeze plug will tap in with a hammer and probably stay sealed up for years, or a little red/black rtv on the plug and push it back it will fix you up good as new.
Feel free to call or text if you have more questions or want me to walk you through an easy check for excessive blowby.

Assuming it’s newer than 1995 it’s the plug where the old school mechanical fuel pump used to be. It popped out for a reason. Really high crankcase pressure maybe. Possible internal engine issue. They don’t just pop out.
Engine is a 1996 international t444e that has been outfitted with the 99 turbo/intake etc.
The more I think about it, the more a serious case of crankcase pressure may be at fault here. It was a tight fit putting it together 5 years ago. I can't remember how the 7.3's regulated crankcase pressure to start to tell how to diagnose.

Thanks for the replies.
Google "ccv filter 7.3", give ya a jumping off point to start fixing I bet.

It’s not supposed to need any sort of anything holding it in place, loctite or epoxy. It popped out for a reason.
:yeah:
I definitely would figure out what's going on with it and not just put it back, or glue it! The 7.3l deserves more than that! :chuckle:

How much pressure is there? I was able to put the plug in with my finger. I have replaced freeze plugs before and I had to use a hammer and socket to get it to seat.
I don't think there should be any pressure pushing out. If I was going to try something, I might get a new plug and put that in the way you're supposed to and see what happens. I definitely wouldn't use any kind of loctite or other adhesive just in case there is something wrong with the engine. If it does have excessive blow-by, it's probably too late anyway I guess.

Could be boost getting by the pressure-side bearing, through the drain-back tube and into the crankcase. That would mean lots of oil in the intake tract under no-boost situations, though. And a remaining turbo life measured in hours, not days.
Just a thought, but that could be a non-catastrophic reason why the plug popped out and isn't showing a lot of blowby at idle. If that's the case, I'd not be cementing that plug in and getting a new turbo pronto.

It would blow out a valve cover gasket or crank seal before it would evee blow that plug if it was excessive crankcase pressure. Most likely plug has been removed and reinstalled at some point and no longer fits correctly. Get a new plug installed in that hole.
Plug has been removed and reinstalled years ago.
I dont think it's a burned piston, the engine that this one replaced burned a piston, and the blow by was atrocious at idle.

I asked my lead diesel tech what he thought. He’s been a Ford diesel tech for 20 years and works on anything from the old 7.3’s to the new 6.7’s. Obviously tough to diagnose stuff over the internet.
:chuckle: Ford service advisor at one of the busiest dealerships in the state, with a expert 7.3 mechanic giving his best guess, and yet internet experts know more than both!
Can’t wait to see how this turns out! My guess is the OP figures out that the engine is toast, Jackelope and the mechanic were correct, and the thread disappears without acknowledgement.. :twocents: :rolleyes:

My guess is the aftermarket freeze plug I installed in that motor years ago has fatigued due to vibration, and either couldn't take the typical amount of blow by that a 7.3 has, or the turbo seals are shot and leaking boost down the oil galleys causing it to blow out. Ive been down the burned 7.3 piston route w few times, and the blow by is amazing. no way that the simple cap test would have passed imo.
Like jackelope said though, tough to diagnose over the internet.

Also it’s interesting to do the oil filler cap test with a ping pong ball rather than the oil filler cap. You can see a lot more.

clearly service advisors know everything, just ask mine, lol.

I put a real small amount of blue threadlocker on the plug yesterday and took it forva drive last night and it did not pop out. I figured with the amount I put on it and it being a smooth surface it would easily pop out if there was any pressure in there. I will try a ping pong ball tonight. I am starting to think the plug was just old and time for replacement. I hope so anyways.
If your going to replace it with another plug, maybe contact ford or international to try and buy their version, instead of the stainless freeze plug I used. That stainless could have fatigued for some reason, or ford may actually use some sort of retaining compound when those plugs are installed from the factory.

I’ve been a diesel tech for 20+ years and seen ALOT of things. I can tell you there will always be something out there a guy hasn’t seen. You just have to use the skills you have acquired throughout your career to diagnose. Anyone that has been in the field knows that diagnosing over the phone or internet is extremely tough. In my opinion the OP needs to find the root cause of why the plug came out. If the plug has been out from a previous repair and was reused that’s definitely an eyebrow raiser. The plug has already been compromised. Those plugs are made to be slightly bigger than the hole diameter. If someone had it out already the plug is at the same diameter as the hole. It’s not going to stay in place. If it had burned a piston you would be getting major blowby plus raw fuel out of the tail pipe and or fuel in the oil from Unburnt fuel plus a miss. Unless it’s a small hole. I agree with deerlick. Excessive crankcase psi will blow a seal long before a plug.I asked my lead diesel tech what he thought.

Stainless steel stretches and does become fatigued. I would buy original Motorcraft.

Engine got ne injector cups, injectors were resealed, new water pump, oil pump, rebuilt the oil cooler, rebuilt turbo... Basically if a part could be rebuilt or resealed, it was. Went together with new valve cover harnesses, new glow plugs etc...

Well good luck! Hopefully it's nothing but a loose plug. I was wondering if someone had changed a bunch of stuff and you changed it back syoungs. That's why I was curious about the sensors. Some guys just buy a bunch of garbage and throw it on the motor and think it's gonna travel thru time.
Nope. This is a T444E that had ~115k miles on it when I got it. I replaced every soft part I could think of building the truck for the future, then sold my trailer and wanted something a bit newer. Ive regreted selling this thing since ive sold it. :bash:

Yeah I have 2 of them. An Excursion with the 7.3l and a 4-door 1999 F350. My babies. My wife drives the Excursion on the daily. Fits my big ass and all the kids with her when we hit the town too!
