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.
is a small amount blue lock tight (lightest tread seal) a bad idea?

look on Amazon, I have two, different sizes.
look at the top of the Piston to see if it has dimples or a hole in it.
that Glow Plug did not bend itself, something smacked it hard, so you need to look inside and see if there is any metal bits laying loose in that cylinder.
Bore scopes come in two styles, one of mine just looks straight ahead, you can cause the end of it to swivel around and look sideways.
the other one has two cameras in it,
* one is straight ahead,
* the other one looks sideways

Ok. Got glow plugs #7 removed no issue, #5 (blew out like previously mentioned), #3 removed no issue and #1 was tough from start and now it’s made it up to what seems like the it’s close to the top and it just spins like it’s stripped threads. All these glow plugs are autolite. What can I do to get #1 out? It’s stuck at its current position and won’t thread in or out like it was installed cross threaded by previous person maybe. It was a not smooth turning like the other two from the start.
any help would be appreciated. Thanks

The glow plug is bent from the force of it blowing out (it is longer than the distance from the head to the valve cover) and being complete, there is no way it touched the piston.
#1 has a swollen tip, hence the reason to only use motorcraft from a reputable source.
you can use a small slow turning drill and spin the glow plug (counter clockwise) while spraying it with GOOD Penetrating oil ie. kryol, pb blaster. Light up pressure then down then up....
until you wear the tip diameter down to fit through the hole.
same thing can be done by hand with needle nose vicegrip pliers. Go slow, very little force or the tip will break off. Just keep spinning it until it shaves enough off for it to come out.
once it is out, install new motorcraft plugs, valve cover gasket then do the drivers side, the longer those autolite plugs stay in the more they will swell.

after I get it all back together do I just start it up? Should I crank it “X” amount of times to clear the cylinders first?
#1 was caked with oil. #3 had oil on it too. 7 did not have any. Any concerns with the oil accumulation difference?
1 was covered in oil. Concerns?
1/4” extension with socket. Spun for about 45 seconds slowly and noticed the plug stated pumping up and down on its own in reverse. Pulled right out.
1 is caked in oil on the left. 3 is oily too.

cool! I really appreciate your drill technique to get the stuck plug out. Went from thinking “gonna have to pull the head, damn” to “I’m gonna finish this, relief”. Amazing how stuck you can get on a single replacement part. The ups and downs when wrenching. Happy I had this experience to share with others and in future moments like this.

Just found this thread and was white knuckling it all the way down! Whew!
Congrats on your repair work.
Great advice @helifixer never heard that method before.
I'd suggest doing driver side too. It's prolly got all the same parts of the same age breaking down.
