compression tool STUCK!!!

[nismostate]

Ok, this is for a 92 Pathfinder. v6 motor. i've done compression tests before and never had this issue come up!!! I took the plugs out vacuumed to make sure theres no dirt. Then put the tester in. did the compression test and it was all fine. NOW THE F$#king thing wont come out!!! IM SO SCREWWED! Im trying to sell this SUV so I can get SR20 soon but this crap had to happen!! HHHHHEEELLLP. Is there anything that I can use to loosen it??? Only thing I can think of is to cut the tube, but man, that would suck!! I haven't used wd40 but I am about to go get some right now. Any ideas would help!! I need to get this thing out before sunday so a buyer can drive it! What's weird is that If i turn it clockwise, it will be a loose for maybe half a turn. but then when i go from there and try to loosen it out, it'll stop completely. My hands are getting burn marks from turning the damn thing so much. the tube just bends.

Oh man, sounds like you stripped the threads inserting the tool. Gotta make sure you put it in straight.

If I were you I'd wait until the engine is completely cold (to contract the metal parts) and then try and unscrew it, but after that I would have no idea. Sorry.

yea i figured that's what happened. i thought it was straight but guess not. i put some wd40 while the engine is cold but still no luck. pretty much screwed. i don't know what i have to do to fix this problem. i want to try cutting the tube but i think i would make the situation even worse. i pretty much turn it as hard as i can and it'll get to the point where the tube spindles up.
