Anyone ever experienced this on a 7.3? I changed an injector on a coworkers truck today and this pulled out on the #8 glowplug harness

POWER-STRUCK · Jul 6, 2013

yes!!!!! uh oh

POWER-STRUCK · Jul 6, 2013

but that is not a 7.3 glow plug

ghohouston · Jul 6, 2013

i know, i just held a 6.0 glow plug i had in my tool box next to it for demonstrative purposes, we didnt have another 7.3 plug, so just left the body in and will have to replace it later. ive worked on hundreds of powerstrokes and never even heard of this happening

POWER-STRUCK · Jul 6, 2013

just hook a trailer to it and work it hard for a couple hundred miles before trying to remove it

ghohouston · Jul 6, 2013

Does it make it more likely to break when trying to remove the body from the head since that middle part is no longer in it?

POWER-STRUCK · Jul 6, 2013

hopefully the tip is still fused to the body!

ghohouston · Jul 6, 2013

Uhh would it not be pretty obvious if it werent? I mean it would be making an awful racket if the tip was broken off in the cylinder

POWER-STRUCK · Jul 6, 2013

yup, or if carbon is holding it in place it will come loose with towing

Had it happen a couple times on high mileage 7.3s. I had a special tool from ford.. Ill look it up.

ghohouston · Jul 6, 2013

Unless im overlooking something completely obvious, when the time comes to replace it, why couldnt I just use a 10mm socket like you would normally? The hex nut ( whatever you call it is still on the glowplug body)

PowerStrokeEnginuities · Jul 6, 2013

Ah! I thought it was stuck in there. My bad

ghohouston · Jul 6, 2013

Nope, we just didnt have an extra glow plug to swap it out with, so we just left it

bad12jr · Jul 7, 2013

I'd have bought a cheaply parts store and left it unhooked vs leaving it broken.

We live in texas, its hitting 100 degrees or close to it daily here, and will be probably till mid october, he isnt gonna notice that one glow plug not functioning for a while. And no thanks on a parts store one, id like to be able to get the tip out of the head when its time to pull out lol

Unless I am mistaken, that is going to leave a compression leak. You need to run to O'Reilly's, they sell Motorcraft glow plugs.

The tip swells from the way it heats when in use. Its not gonna swell if its unhooked.

Looks to me, if you remove the center section, it is the tip. It is leaving a hollow tube in the head. Every compression stroke, you will be pumping compressed air and fuel up under the valve cover, thus missing that junk with oil. Not a good scenario, go spend 12 bucks on a glowplug.
