I was changing my spark plugs and encountered that i was not able to screw out the last spark plug. It is stuck like as if the previous person (not me) over tighten it and now my spark plug socket can not reach the spark plug. Its a little hard to believe me but its the honest truth. What are my options?

Note: i think the last person who changed them did it while the engine was HOT and the metal expanded and was able to tighten it more than it should have been. Now that it has cooled i am not able to even grasp the spark plug with the socket.

 

If your theory about the last person who changed them is correct, why not try taking it out while the engine is hot? If your're careful you wont kill yourself...

I'm confused about this:
What has happend that all of a sudden your socket can't reach the plug??????
It will come out, try using a breaker bar instead of a ratchet.

 

Yikes, or what if the socket IS reaching the plug but it just doesn't feel like it because the threads on the plug are rounded. Yikes, what the hell do you do if that happens?

 

check the bottom of the coil boot that you pulled off of that plug. if the bottom isn't on the boot, then it may be still on the plug preventing you from getting the socket on the plug. compare the boot to another to see if they look the same.

 

Attempt to hammer a 12pt socket on the plug, or yank the plug tube to give you better access is my best guess.

 

Double yikes

Hypotheticaly, youd have to see if the plug could be removed without drilling it out/tearing the engine down. Either way, the only way to determine that would be to remove the UIM/valve cover/CAMS.

Not a bad idea.

 

Yikes, either way doesn't sound fun. All the more reason to change plugs with the engine cool, torque them properly and use anti-seize.

 

Pour some PB blaster into the plug well.. Let it soak for sometime and then use a cloth wrapped around a stick to cleanup any residue. Put back coil and start engine to heat up the surface and retry removing the plug.

 

Seems like the absolute most likely scenario....jeez you guys got the poor guy with a rounded plug thread lol....your gonna give the dude a stroke.

 

I just changed my spark plugs again. And the above quote was the EXACT problem.

delaman_17 fix: Get a pointy screw and tie some string around the head of the screw. Next "screw the screw" inside the bottom of the stuck boot by twisting the screw with a screwdriver. Next pull the string and the bottom of the boot will come out along with the screw. Replace the entire boot. Done and done.

 

I have a similar problem... the bottom of the boot has corroded or melted and is broken inside the cavity in which the spark plug sits, thus i cannot get a socket onto the plug due to the broken piece still melted inside there. Any suggestions?

 

Have you tried the suggestion above for this exact situation?

Have you tried grabbing it with pliers, a pick, anything?

 

^^That.

Find a pair of long, thin pliers. Grab the boot, remove the boot

 

i did try the screw and string. i tried a pick before i looked on here and saw the screw idea. ive tried it cold, ive tried it hot hoping the piece would soften up.

 

Nightmare sounds like time to pop the head.......good luck OP

 

If the boot is stuck, put some crazy glue on the coil stem and put it back on the plug.
Wait 5 minutes.
Pull the coil out with the boot attached.

Same principle applies if it's broken. Use some ingenuity.
