Broken Spark Plug - Need help fast

Assuming you were using a spark plug socket and not just a regular deep socket that happened to fit, we see here the downside of: 1) Ultra-extended spark plug intervals 2) Champion spark plugs > What can I do to remove this, I've tried my tap and die, I could not > move it.

First choice in penetrants is Kroil, but you're not likely to find it locally, so go get a can of Mopar penetrating fluid P/N 4318039 from your dealer. I've never figured out what they put in this stuff and it has a truly bizarre smell, but it works very well. I'm not quite clear on reading your description where the plug broke off. I'm assuming it sheared right off right *BELOW* the hex section? Are you left with a solid plug, or with a ring of metal? |

If getting stuff in the cylinder is a big fear, why not take the head
off? You lose a little bit of leverage that way, but at least you could get at it from both sides..... Just an idea, I'm no expert. |

I agree, head removal is the propper way.
I ran into this before with an aluminium head, its just not worth it to drill the core with head in place. If all the ducks are lined up (parts, tools etc) its an easy job.

By the way, there are two important processes that should be considered with
aluminum heads and steel spark plug threads. 1. the different rate and extent of thermal expansion :heating and cooling might break the corrosion bond 2. electrolysis between dissimilar metals causes corrosion between the surfaces. : there are compounds that should be applied to the plug threads to reduce the effects of electrolysis.

Why would Champions be more prone to cause this problem?
