Launching a glow plug?
Hey, Just picked up a 1986 F350 that was somewhat taken care of. It drove kind of rough on ride home. Glow plugs didn't work, no muffler and white smoke with any RPM revs. Still I bought it?? Cleaned Motor, Changed oil ect... I Read about all the horror stories here dealing with glow plugs, and decided to replace them. Of course they are Autolites and I had a tough time getting some of them out ( 5 were pretty well deformed ). I had to use a cats paw to yank one of them and about a whole can of PB Blaster!
Well, Number "7" against the passenger firewall broke its tip. Piston is at TDC, I removed injector and rigged up air hose to injector hole to see what the deal is and no air came though to GP hole. I filled GP hole with PB blaster and also top of piston. 2 hours later: no PB Blaster in injector hole anymore (seaped past rings), But the GP hole is still as full as before. 1).Can I hope the deformed tip will be fine where it is?Will it stay stuck? 2). Heat up the GP hole and try vacume/air method, but if its deformed like the others.. there's no way this will work.Will it? 3). Should I install the injector and FIRE IT UP??

I been thinking... If the Glow plug tip is stuck in hole because it is a deformed autolite and/or stuck with carbon. I should be able to tap it down into the chamber so I can Vacume it out. Cylinder is at TDC. Does this sound right???
Thanks
Thanks

You may be able to poke it down and then vacuum it out.
You may be into removing the head to get it out.
My luck would be remove the head to get it out.
I have heard several stories about drill bits, running the engine till it pops out, chucking it in a drill and several others.
How lucky are you?

Got tip out!!!!!
Well I had the cylinder at TDC and used a nail set punch and smacked down good for about 5 min till the distorted tip fell into the head (pre chamber). I was pretty scared about the air hose and vacume trick........... Worked great!!!!!!!!!!!! when I opened the Vac and saw the tip I was psyked!!! put in the last Glow plug and she ran like a really well.
