Greetings from Mississippi! Hey I am working on son n laws 1996 F250. Laundry list of stuff on this hand-me-down truck. I got the A/C repaired, water pump changed & before I tackled all the valley fuel leaks I decided to figure out the glow plug system. This truck never started when it's cold out so I had installed a coolant heater in the lower radiator hose for a short term fix. Relay checked OK. But no continuity to ground at injector terminals so off with the covers! Yeah they all check bad. I started removing them- right bank- and number three came out harder than the rest. I looked & the top of glow plug was laying beside injector. The outer body had un-screwed from around the heating element & left it in the head!I theorize I'm screwed now...I've not tried to remove it yet, tomorrow I will remove rocker assys & injector but I'm not usualy lucky enough be able to remove something like this. I spect the head gonna have to be removed & element removed form the bottom.
Anybody else had to deal with this same problem? Thanks!
PS- In the meanwhile his 1120 Deere tractor started missing & it is in the shop also now. What I thought would be an EZ injector re-seal job has turned into a head gasket replacement! In the big picture just trying to help people always brings to mind the old sayin- "No Good Deed Goes Un Punished"...

 

Say what now? The outer steel casing of the glow plug unthreaded from the head but the center element is stuck in the hole? Tie something on it or wrap a ball of string around it, whatever to prevent it from dropping in the hole. Make sure the range is clear and crank the motor. let compression blow it out for you.

 

You got it! Just a piece of wire poking up from the hole a little bit. I can lay a furniture quilt over the right bank & if that works maybe I won't put a hole in the hood...I popped a couple from a 903 Cummins some long years ago...I saw the boss stopped one day scratching his head looking at that hole in the wall at the end of the shop...Never did tell him how it got there!

 

Ehh, it's your son-in-law's hood. Just tell him it's one of those bullet hole stickers, or better yet just put a bullet hole sticker over it. Then you won't be lying. I'm all about the "what you don't know can't hurt me" philosophy.

 

Or get a grip on the GP remains with drill and very slowly reverse it out of the head. Idea is to slowly grind off any swollen GP tip and get it outta there.

Pics would help.

 

Two days late to this party, but I'll add to fill up the glow plug hole with a penetrating oil and let it soak for a while before attempting to spin that heater element out of the cylinder head.
