Well, I call it a butane torch, but it has a map gas tank on it :eek:. I think I'm going to try getting it out here shortly, and if I dont get it to move I think I'm going to take it for a drive to get it up to operating temp and see if that doesnt help me out. I think it will, how much is another story :D. My dang left palm sure is bruised and sore after lastnight LOL

I would just run the engine up and get it up to temp. Locally heating with a torch isn’t gonna get the aluminum expansion you’re looking for. You shouldn’t have anything to worry about driving it.

Well i got the glow plug out, but the back 1/3 of the threads (deepest into the hole) got biggered up pretty good. Anyone know what thread these are? Thinking about getting a Drexel tool and cutting two slots on a new glow plug and using it as a tap

I guess you learned your lesson the hard way. I only remove mine after my 60 mile commute home after marinating the area in pb blaster a week prior.

Well, I got the old one out, but it messed up the threads. Nothing a dremel and some patience can't fix!

Well, theres one more original glow plug that wouldnt come out a year ago when I replaced the other 6. SO, the day it fails I guess we will see if I get the same result. Next time I'm finding myself some Aero-Kroil though. I'm just happy I was patient and didn't make a shitty situation any worse.

If i have to make a on the fly tap, I use a grade 8 or metric grade 12.9 bolt. Much harder material then the glow plugs.

Also, the last time I did mine, I put anti seize on them. After a year or so later I checked them and they came out real easy.

I had a source about 1.5hrs away with helicoils, taps etc for redoing the hole if I screwed it up to the point I couldnt get a GP in. So I just went for it, and thankfully it did the trick. But yes, the GP material isnt very hard at all.. Hoping this thread helps others in the future.
