Oh, and in the worst case, you access the pre chamber through the injector hole. Head removal is neither required nor particularly useful.

84 K20 "Ethel" Not an Sbc/NV4500/241C

Semi restoration of a 1984 K20 pickup.
5.3 LS, nv4500, np241c.
Ok thanks guys I got 6 replaced and anti seize the crap outa them too but still working the mushroomed one out.
I don't feel it making squat for progress... dammit..
She runs again and no coolant seeping out of block and fires right up! Drove up and down my hill and zero issues. Thank god that's done!
If anyone is wondering I pushed the tips into the cylinder and fired it up. I guess I'm lucky?? But It seems fine..
Used to be done all the time around work, they said they'd make noise for a very short period then be quiet
That's basically what happened. I heard it rattling and waited for the hole in piston noise but it never came?? So I drove it and it's gewd..
now onto a heater core before snow missions.. any tips? This is a non factory ac truck.

Typical story. It's not great for the engine, but really your biggest risk is having the wire scratching things. It's not a solid piece like if you dropped a bolt into the cylinder. It's a crumbly piece of ceramic-covered toaster wire.
It's ingested metal before! So I'm whatever at this point because it's been an SoB..
Heater core...my tip is that it's nice to have one. And a blower that works (unlike mine
)And non A.C. is nice from a maintenance perspective.
It has the retrofit for the ac which I am undecided on fixing because I have the ac box from the blazer which I could get an evaporator for.. a project for another day.
Does this interest in "snow missions" mean you're not yet selling the truck? 
Well not broken, and it's the only capable 4x I own so it'll stay until whenever. Still figuring out the figure out. Too many irons in the fire right now but one things for sure I got it going again.
Buy the truck, it come with it and the 6.2I am kind of looking for an under dash A.C. retrofit system at the moment...
Buy the truck, it come with it and the 6.2
Nope. I already have too many vehicles. Probably even too many trucks. Definitely not interested in a vehicle that can't carry the family.
Plus, the fuel bill to drive it over here would double the cost of the truck!
Dude. The family can ride in the back and the truck is worth way more than the fuel, it'll go 600 miles on 40 gallons, and I dunno how far you are away but it'll be cheap..
My 6.2 has had only 7 out of 8 glow plugs since 2003...one up front on the passenger side unscrews and will come out about 3/8",but wont come any further--I have tried every thing I have read online and thought of myself to get it out without busting it off,but to no avail..
Vise grips,I pried on them with a bar,even stuck the glow plug in my electric drill chuck and ran it in reverse while I pulled outwards on it..for a good 5 minutes,with zero success..its dead too,so its not like I can plug the wire back on and say "good enough,leave it".
I have not tried the official 100 dollar "glow plug remover" tools offered by OTC and various other online sources,and wont,unless someone had one I could borrow..
My bet is the dam thing will bust off regardless of whatever tool or method is tried,the thing is probably expanded to gigantic proportions or bent at a 90 degree angle or something..my injector lines will likely break off if I tried removing them and the injector too,so I just assume leave it alone..
Every year about this time it needs a few new glow plugs,and I give it another go,try to get that one out--about 2 weeks ago I decided to unscrew it after a 25 mile ride and try removing it again..hoping being hot it might finally come out..
--no luck --I even tried starting it up with the glow plug unscrewed and floored it 4-5 times and it only puffed compression out on the first stroke,then ran normally like it was still screwed in!.
I was not brave enough to drive it around that way,but chances are it was not going to blow out intact like I hoped it would..also feared it might break and do damage to the cylinder and piston..
It has already had one glow plug in the #3 cylinder decide to shatter while I was driving it a few years ago,and it sounded horrible!..
I limped it home 3 miles clattering,then when I was close enough to home to walk to it, I floored it several times in first gear till it hit the govenor--at that point I cared not if it blew up.(and kind of wished it would)....and it quieted down,I guess the chunks blew out the exhaust,but I wouldn't be surprised if it wounded the piston or cylinder some...
I think a push rod may have got slightly bent,it has a loud lifter noise after a cold start for a few minutes since that happened..
Glow plugs just plain suck on 6.2's,and most diesels period...they should have made them as big as spark plugs,not with puny 3/8 hex heads that rot away quickly and tiny 10mm threads...
I have had more rust away than fail electrically ,I had to replace them while they were still able to be removed,the hex was whittled away to a nub on several of them..they still glowed fine ,but if I left them in much longer it would be hell to get them out..

Seems like they're cheap enough to do at shorter intervals or at least check them because in the case of them being n/a their easy to get to just like spark plugs.
Cheap ?...10 bucks each isn't cheap when 8 spark plugs cost maybe 15!.
Also I do not think they are easy to replace,especially on my Suburban with A/C,the rearmost right side ones SUCK to get at..
Unfortunately most people leave glow plugs in until they are dead, or rotted so small its a major undertaking to remove them..then I buy the truck..
