Attention diesel techs!

Hello, my friend has a 96 f-250 with a 7.3 stroke. He went to change his glow plugs and to his surprise the dang things were stuck in the head as in they uncrew but are still stuck like the ignitor part is in the combustion chamber. Well, he got one out and on the next one the glow plug came out all but the tip it is stuck in the chamber still. He was advised to crank it like taking a compression test and see if it would blow out. It didn't and now only thing we know to do is pull head

Is there anything anyone has done to keep from pulling the head I mean like some type of trick or something. I know of some old diesel techs that said this isn't a real uncommon thing to happen on trucks with higher mileage but they said pull heads. I know if there is a will there's away that someone has figured some kind of way out maybe

Don't think anyone that I know of has had enough will to figure out a way. Pull the heads. JJ

yea because the compression of the engine could possibly force it out the hole backwards I know kinda sounded scarry to me as well but came from ford diesel tech 30 years experience

I could understand this theory if the tip was still stuck in the hole and it was lined up just needed a little push of compression from the back side but if the tip is just floating around in the chamber then NO DICE!

And what happens if it gets sucked in??

I know it sucks, but pull the head. I know of a few people that used a thin punch and knocked it into the cylinder. Replaced the glow plug.. and fired it up.

Didn't work out so well.

Pull the head.
