I'm no car expert so pardon the ignorance. My kid ignored those warning lights designed to tell you to have your vehicle checked and now this. Top middle ignition coil basically melted and caused the vehicle to die (burnt fuse). Bought a new coil to swap it and figured I'd change the plugs at the same time. Pulled 2 of the top plugs with no issues, but the one where the coil melted was also very badly damaged and I cannot remove it with conventional methods. I need some help with this, any removal tools someone can suggest? I've attached a photo. Also, I don't want my new parts to melt once I get them installed, so if someone can tell if something else may be the issue that could have caused this or any suggestions of what else I may want to do along with changing the plugs and coils please advise. Thanks! Jason

 

Wow in my 7 years as a honda technician I have never seen plugs melt on a v6 , and I thought when I had a 09 si spit a plug tru the hood I thought my selft I have seen it all


I know ford has a issue with their 4.6 and 5.4 windsor engine braking plugs at removal , try to use that

 

Can't believe you have never seen this? I've seen this for years at our shop, sometimes you get lucky and you can get it out, sometimes not and you need to remove the head and remove it that way and have a machine shop fix the plug hole. I assume that is melted debris from the coil and then the rubber boot that is at the end of the coil is probably there as well. Your best bet is to get various long pics, Mac and Snap on have a kit with
Pics with various angles that you can chip away at it, also spray in some pb blaster to loosen up the rubber boot, pick at it with the pics and blow compressed air to blow out the chips of plastic you are breaking out, eventually you will get to the rubber boot, you can usually get it with the pic and pull it out, then pull the plug out.

 

The reason that melted was that the spark plug backed out and the gases melted everything
Seen this numerous times on v6
Most of the time its the middle plug on the front or back head

 

Agreed. This is a known issue discussed on the ROC (ridgelineownersclub.com).

 

Also a known issue over at piloteers.org.

I've done about 4-5 so far with one needing a short block due to the cylinders and pitting on the piston, the others got a new cylinder head due to the damaged threads. It's usually cylinder 4/5 and its caused by spark plug failure.

 

Gases melted everything?wtf

The spark plug backs out enough to arc against the cylinder head and weld itself in place. Had it happen on our 2006 Pilot w/ just under 100k miles. It did make a ticking sound prior to this happening, which I thought sounded very similar to a loud lifter. But after this occurance the sound is gone, which makes me think it had something to do with the plug.
