glow plug stuck

[cr125rider1988]

Last night a buddy and mine chaned the glow plugs in my truck. It was a pretty easy job..... Until the middle rear glow plug on the passanger side was locked. I made the executive decission to leave that one since all the other ones were easy and came right out. When i started the truck (with the valve cover off) you could see a couple small bubbles coming from the frozen glow plug. Not really sure what to do with this situation. The truck starts real nice in the cold now, but I am not sure if i should leave that one? Try really hard to get it out and hope it dosnt break? what to do what to do???

Vice grips, if you break it tho your gonna end up pulling the head to remove it

Sounds like a fun time! :S

I would have soaked it first in penetration oil (will burn with fuel one if any gets in compression chamber). Leave for a while then TIGHTEN about an 8th (if that) first just to "break" the seal. After that then obviously loosen it off and replace with new.

Where you the person who installed the old plugs? There could have been a number of issues with your frozen plug. Last person might have used thread lock if it was leaking or maybe cross threaded the plug. Good luck

Is it not even loosening? Or is it threading loose, but sticking when you go to pull the plug out?
