seized sparkplug Options

[aflacattack]

my number 2 spark plug ceased and i cant get it out without absolutely torquing on the thing...(which i dont want to do)
any ideas?

edit: the guy i goto says that it is probably from over tightening and he doesnt think dumping some wd40 or any penetrating oil down there is gonna help, any other ideas?

seized? ceased means its stopped as in stopped working as in no spark.


seized is different, it means stopped as in not moving as in not turning.


and trust me, if the seal between the plug gasket and the head is enough to keep the thousands of PSI of pressure created by combustion from seeping past the threads, then it wont be letting in any penetrating oils which only have gravity backing them.


a seized plug is a heck of a problem, but as i said, go back and forth. even if it doesnt move at first, just work it back and forth with a breaker bar. keep doing that back and forth and it'll get broken loose eventually.

its that or snap it off in the head and deal with that. if you're lucky it'll just leave the threaded part in the head and someone can get an extractor into that and turn it out. however with either way, i suspect you'll need to run a thread chase down the plug threads at minimum, if not get the head drilled and a threaded insert installed. helicoils suck for heads, a real insert is the way to go. they make special copper ones just for aluminum heads or some other metal just for aluminum heads. steel ones like helicoils are not to be used on aluminum heads due to different rates of expansion between the metals.
