Re: 99 7.3 Hydro locked after changing glow plugs?
water in your cylinder is probably the injector cup seal yes
The injector cup separates the coolant from the injector body, if you disturbed that seal then it will leak coolant into combustion chamber
I'm pretty sure the glow plug housing goes through the water jacket as well but unless you punched a hole in the head there its not going to leak coolant.
What did you do while you were in there near cyl #1?
You mentioned you "messed with" injector #1 what does that mean?
